Windows 10: Windows 11 won't reboot after program installation

After I installed a program, Windows 11 won't boot up.

I should have cancelled the installation, instead of finishing it. Tried going into restore and I have the bitlocker code, then it says I did not enter a recovery date, but it doesn't give me the options to select one. Tried just about everything in the advanced options menu and nothing works.I appreciate any info to help me get going again. This is a 3 month o

Hello. I´m having this issue since installed one of the latest Windows 10 system updates.

When I try to open any program that requires Administrator confirmation (that screen with the Yes/No question), this dialog won´t appear anymore. The screen background stays darkened and nothing happens.

1. Using Windows 10 Home (x64)
2. My microsoft user account is properly checked
3. I´m the administrator of the PC
4. Already tried do create another administrator user account - same problem, no success
5. Cannot start any program/service that requires administrator authorization (not even regedit)
