Hi NagumoHayaki.
Thank you for reaching out here in the Microsoft Community.
In your description, your computer encountered a Critical Process Died error.
Typically, this is a blue screen error (BSOD) encountered prompt.
I noticed that you tried everything you looked for. If you can, please describe for me which methods you tried.
You mentioned that it was a corruption on the System Drive SSD.
If you are unable to log into Windows right now, you can refer to the following steps and try to boot your computer in safe mode
Windows startup settings - Microsoft Support
If you are able to log in to the system, you can refer to the following steps to check the drive and confirm this
Search for cmd and run it in administrator mode
Type chkdsk c: /f
Wait for the check to complete and see if it checks and fixes the problem.
Disclaimer: Running chkdsk can check the file system and file system metadata of a volume for logical and physical errors. To avoid any trouble for you, do not cancel or interrupt chkdsk, and back up important data.
More information please refer to this chkdsk | Microsoft Learn.
If the problem is confirmed to be with the hard disk, please make a backup of the data and then format the hard disk to see if the problem recurs. If the problem still exists, it is most likely an internal failure of the hard disk, please contact the manufacturer of the hard disk to have the hard disk inspected further.
If the problem does not appear during the checking of the hard disk, you can also refer to the following steps to collect the blue screen logs and share it with me.
1 Tap Window+R and type sysdm.cpl
2 Go to System Properties and tap on the Advanced tab
3 Find Startup and Fault Repair, tap Settings
4 In Write debug information, select Small memory storage
5 The following directory will change to
%SystemRoot%\Minidump
You can memorize this location and if you experience the blue screen again, you can restart your computer and enter this location into Explorer and you can see the .DMP file created under the folder.
You can refer to the link below to share the .DMP file via OneDrive.

If you are not using OneDrive, please also let me know and I will initiate a private message with you where you can upload the blue screen logs directly to me.
We will provide further assistance to you after analyzing your blue screen log file.
Thank you for your understanding and support.
