Help: BSOD Critical Process Died Cannot Log into Windows 11

I am at the end of the rope with my current BSOD issue and any help would be appreciated. 3 days ago I was getting a "Class not registered error" on any media app (MP3, MP4, etc). I tried the basic workarounds within Windows 11 and nothing worked. So I did a system restore. Ever since then I'm unable to log on to Windows as it goes directly to BSOD "Critical Process Died." I've tried the following:

1. Automatic repair is "Your PC did not start correctly:
2. Startup repair couldn't repair your PC
3. Both "Uninstall Updates" are "we ran into a problem ... "
4. Safe mode does nothing. BSOD
5. System Restore gives me the "You must enable system protection." When I go to command prompt and do the "restrui.exe /online ..." workaround, it now sees the C: drive restore point but fails to restore.
6. DISM check/restore health, etc., gives me "cannot find the file specified" and 'Could not repair."
7. Chkdsk /f gives me "write protected" cannot fix. Every workaround does not fix
8. Reset this PC (the last thing I wanted to do as I have massive apps and plugins) gives me "there was a problem resetting your PC"
9. I ran a boot rebuild through a 3rd party app vis USB stick. Rebuilt the MBR successfully. Same result. BSOD

I've resigned myself to the fact I will probably have to format and reinstall a fresh windows, which will set me back a week. But 2 problems:

1. the computer is only 3 months old and a recent upgrade. Is there, and how would I find out, a hardware issue?
2. I took out the SSD and used a USB reader to access it from another computer and it read fine. I did a surface check which checked out fine. I ran a system hardware diagnostics through BIOS and everything checked out fine. Could it still be a hardware issue?

Any help would be most appreciated. I have everything backed up so I will lose no data, but since I run a recording studio, the amount of time reinstalling is a potential nightmare, especially since I just did it 3 months ago. And I don't want to start over on a potentially unstable of damaged system. Thanks for any help in advance.

PS ... I could not run log collector via USB stick. Any help with that? Thanks

"the operating system could not be loaded because the digital signature of a file blah blah blah"

and it won't let me do much else.
exactly same as yours. Wont roll back updates. Running sfc /scannow finds errors and fixed them every time it's run.

The drive is less than 6months old a samsung 990 pro evo. It is monitored and shows as 98% health in HD Sentinel and Crystal disk. The health just being due to so much data written.
