As a workaround, if the upgrade is within 10 days, you can try going back to the previous version of Windows 11. To do so, right-click Start->Settings->System->Recovery. Select "Go back", and follow the instructions.
You can also restore the system to a restore point. To do so, press Windows+R and enter "rstrui". Select a restore point before the issue, and proceed with the restore.
Thanks for your patience and understanding.
