Thanks, but still no joy. Settings still crashes.

Did you reboot after you performed it?

No, not at all, just saying after going round and round with my issue on my Beta builds that was what I got from Co-Pilot after trying everything else. Apparently per Co-Pilot settings bugs are an issue for some on insider builds.

Just to be clear, I've never been on "insider" builds. I "upgraded" to the current build only because it purportedly fixed the CAM db file size problem I was having, which in turn was impacting my WiFi connect time. The Settings app was crashing under the previous older version, which was not "insider".

No, I did not. I just now did, though, and the Settings app crashed,so, after rebooting, no joy.

Try these one at a time in admin command prompt.

Code:

DISM /Online /Cleanup-Image /RestoreHealth

Code:

sfc /scannow

I've done these steps several times. See posts 9 and 10 in this thread. Should I do them again?

No need to do them again.

Could let Windows Update reinstall Windows as you would not lose anything.

Setting > System > Recovery

Do you have a usable Point-in-Time Restore or a Restore point prior to the crash?

Have you ever shut down the system completely after an update or just rebooted it? If not, then do it.

I re-installed Windows (or is it "reset"?) using this approach as part of my long wrestling match with the WiFi connection problem. A relatively short time later, we learned that the WiFi connection problem was being caused by the CAM file size problem, so I was led to try to stop location services and delete the db-wal file as a workaround to manage the size of that file. That's when I discovered that I had this Settings crashing problem. Until then, in the four years or so since I've had this laptop, I had never had occasion to traverse the settings app to the location setting. It may have never worked, may have stopped working when I upgraded to Windows 11, or it may have stopped working when I did the "reset". But it is not working now, and I'm pretty sure I haven't done anything to cause it to quit working.

I'd rather not do this again unless absolutely necessary. Although I didn't lose any data, a few things got changed, and it took some time to reconfigure the computer to my liking.

No.

I shut it down completely almost every night.

Have you tried resetting the permission cache via the registry? HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore
You'll see subkeys for Webcam, Microphone, and Location.
Right-click the ConsentStore folder and select Delete.
Don't worry, the next time you access your camera or microphone, Windows will recreate this subkey and simply ask for permission again.

I have not tried this, but I will note that, as part of my interaction with ChatGPT, I created a new user and tried to access location, camera, and microphone privacy settings, to no avail. I don't know a lot about the registry, but changing a setting under "Current User" seems unlikely to "fix" my problem, which happens under a completely new user. If I'm not understanding this correctly, please advise and I'll try it.

I'll also note, for completeness, that I don't have a working camera. The installed camera on this laptop failed very soon after I bought it (but out of warranty). Windows can't find it and doesn't install a driver via updates. Thus, I could understand, I suppose, why the camera setting would crash the settings app, but not location or microphone.

What is the status of the services (Running / Disabled)?
1. Network Connections Broker
2. Connected Devices Platform Service
3. Capability Access Manager Service

All "Running"

A Windows reset will only keep the drivers and reinstall Windows removing your data. If Windows have an issue it might not be fixed. If you consider doing another reset, I suggest you format the disk and do a fresh installation instead. It will get rid of any issues you currently have and start from scratch. As you realize that will take a lot of time, so I would try an in-place upgrade/repair first using the ISO.

Lavik · 2026-07-05T12:42:18-0400

Hmm.. I don't know how you'll take this advice, but the best solution without losing data or programs is an "In-Place Upgrade."

Jim Rockford · 2026-07-05T13:03:37-0400

Well, fixing this settings crashing problem, considering it only affects location, camera, and microphone, is not worth the disruption that will be caused by "re-installing", in whatever way, Windows. The last time I did this it only disguised the WiFi connection problem by effectively deleting the db-wal file. The file size continued to grow after the re-install.

Unless there are other approaches from the collective, I think I will try the CAM database "rebuild" and report back results. I may put that off until tomorrow.

I continue to appreciate everyone's thoughts and ideas. Thank you all.

The Windows Settings app (SystemSettings.exe) is designed so that when you click on any of these three sections ("Location", "Camera", or "Microphone"), Windows uses the system service (camsvc) to perform a hardware poll of all media devices connected to your laptop.
Because your webcam is physically damaged (likely due to a short circuit in the cable or a burned-out controller):

1. The system poll hangs indefinitely while waiting for a response from the dead camera chip.
2. The Component Object Model architecture (combase.dll) hits a timeout and forcefully terminates this infinite loop with the exception code 87af000b (App Crash).
3. As a result, the entire Settings app crashes, even if you only intended to open the Microphone or Location menu.

Since the camera does not show up in the Device Manager under normal conditions, you cannot fix this by simply deleting the driver. You need to isolate the dead camera from the OS polling chain either physically or programmatically.
Here is how you can resolve this issue:
------------------------------
## 1. Disable the Built-in Webcam in BIOS/UEFI (Most Reliable)
Disabling the camera at the motherboard level forces the CPU to completely ignore that specific port, stopping Windows from attempting to poll it.

1. Restart your laptop and repeatedly tap the BIOS key immediately upon powering it on (usually F2, Del, or F10, depending on your laptop manufacturer).
2. Look for a section named Advanced, Security, Configuration, or Integrated Devices.
3. Find an option called Integrated Camera, Webcam, or Front Camera.
4. Change its value to Disabled.
5. Press F10 to save your changes and exit. Boot into Windows and test the Microphone settings.

## 2. Force-Delete the Hidden "Ghost Device"
If your BIOS lacks this option, Windows might still hold onto old registry logs of the malfunctioning camera and keep trying to "wake it up."

1. Right-click the Start button and select Device Manager.
2. Click View in the top menu and check Show hidden devices.
3. Check the Cameras, Imaging devices, and Universal Serial Bus controllers sections.
4. Look for a semi-transparent (hidden) camera icon or a device with a yellow exclamation mark named “Unknown USB Device (Device Descriptor Request Failed)”.
5. Right-click it, select Uninstall device, check the box that says “Attempt to remove the driver for this device” if available, and click Uninstall.

## 3. Block Camera Inquiries via the Windows Registry
You can programmatically forbid the Capability Access Manager service from ever requesting access to the webcam.

1. Press Win + R, type regedit, and hit Enter.
2. Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\webcam
3. On the right side, find the string named Value (if it does not exist, right-click an empty space -> New -> String Value, and name it Value).
4. Double-click Value and change its data to Deny (instead of Allow). This blocks any internal system attempts to query the camera, preventing the combase.dll crash.

------------------------------
## Alternative: Bypassing the Settings App for Microphone Adjustments
If you need to quickly configure your working microphone while the Settings app remains broken, you can bypass it using the classic Control Panel:

1. Press Win + R, type control, and press Enter.
2. Set the top-right View by option to Large icons.
3. Open Sound and switch to the Recording tab. Here, you can change your microphone levels, set default devices, and test your audio without touching the buggy UWP Settings panel

Well, this seemed very promising, but, after steps 1 and 2, above, no joy. Is step 3 necessary?

My laptop is a Dell Inspiron 7390 2n1. Access to the BIOS is via F2. Once there, I navigated to the "System Configuration" section and found a setting for "Enable camera". It was "on" so I turned it off. I saved the changes and booted into Windows. I tested the Settings app and it crashed right where it always has.

I next went to device manager and searched for hidden or ghost devices as instructed. There weren't any.

So, I'm back where I started. Do I need to apply the Registry change? I want to make sure that's necessary before I fiddle with it.

Thanks for the suggestion. I really thought it seemed promising!

Yes. What have you got to lose? If that doesn't work either, then simply delete the created registry key.
