Keeping computer awake for 7 hours to log data

I have an ESP32 microcontroller connected (via USB) to my Windows 11 Home laptop computer, and I am logging sleep data for about 7 hours through Tera Term (which is on my laptop). On my laptop (last night), I went to: Settings > Power and Battery > Screen and Sleep, where I set the following:
When plugged in, turn off my screen after: 5 minutes
When plugged in, put my device to sleep after: Never

Unfortunately, my Windows 11 laptop evidently went to sleep after 3 hours because when I awakened in the morning (after about 6 hours of sleeping and supposedly continuously collecting data on Tera Term), I had to press the power button on my laptop to illuminate the screen display and enter my Windows Hello Pin password to access my desktop screen where I discovered that my Tera Term program had quit collecting data after almost exactly 3 hours (actually 3 hours and 22 seconds). I do not know if I am failing to do something on Windows 11 correctly so that my laptop will stay awake throughout the night (with the screen display unilluminated and with my laptop plugged in all night long) and thereby allow Tera Term to continuously collect data, or if this is a glitch in the Windows 11 OS. Any advice would be greatly appreciated. Thank you for your time.

You have to go edit the advanced power plan settings:


You, have to find this section and disable both sleep and hibernation:

You can install MS PowerToys which has function to keep PC awake:

PowerToys is an option too, but I personally prefer to not to install any extra tools since all this is already built in to Windows and just require you to find the correct place to configure things in.

BTW, my laptop stays online 24/7 and only reboot because of an update.

@SlicEnDicE
PowerToys has several functionalities that don't exist in Windows, like keeping windows of choice always on top.

I also do not like installing any software and doing stuff myself but this is MS's product and it's quite useful.

Add to reg. Edit advanced power options and set unattended sleep to 0 to disable it.
