Help! My Windows 11 Won't Start and I'm Getting Error Code 0x7E

I'm having trouble starting my Windows 11 device. It keeps giving me the error message: "Your device ran into a problem and needs to restart. We're just collecting some error info, and then you can restart." The stop code is SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E), and it mentions that vgk.sys failed. This file seems to be related to Riot's anti-cheat software. The weird part is, everything was working fine yesterday, and now, when I try to boot it up today, I just get stuck on a black or blue screen with self boot options. I can't apply any fixes since Windows won't even start. I've tried uninstalling old updates, but nothing has worked so far. Is there a known issue with this, and what can I do?

It sounds like a tough situation! Have you tried booting into Safe Mode? If you can access the automatic repair screen, you should be able to open Command Prompt from there. In Command Prompt, try running "/scannow" to check for and fix any corrupted files. Just be cautious: any changes to system settings can risk data loss, so make backups if you can!

To boot into Safe Mode on a normal PC, reboot your system and as it's starting up, keep pressing the F8 key until a menu appears. You can then select Safe Mode from that menu. If that doesn't work, you might have to use a recovery drive or installation media to access troubleshooting options.

You're definitely not alone with this error! The vgk.sys file being mentioned might be throwing a wrench in the works—it's tied to Riot’s anti-cheat software. If you can somehow boot into Safe Mode, that could give you the opportunity to uninstall or disable the software. If Safe Mode isn't accessible, consider other recovery options.

If you're completely locked out of Windows, you might need to focus on the dump files for diagnosing the issue properly. If you ever get the chance to boot into Windows or Safe Mode, check the C:WindowsMinidump folder for any crash logs. You can zip those files up and share them for better analysis on what went wrong.
