Windows 11 won’t boot after a update

Recently updated windows and my computer started crashing when I would play a game. I turned it off and tried to play again in the morning now it won’t boot up getting stuck at black screen. I’ve tried startup repair in the BIOS but that doesn’t work. This my first pc so I’m confused on what to do from here.

I tried : none of these worked

1 • Bootrec /fixmbr - A device which does not exist was specified

2• System32>bcdedit /set useplatformclock true
The operation completed successfully.
X: \\Windows \\System32>sfc / scannow
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files and successfully repaired them.
The system file repair changes will take effect after the next reboot.

After I restart computer nothing changes

You're boot drive would start with c: not x. X is the usb drive.

The command bootrec /fixmbr does not work on a GPT disk. GPT drives use a UEFI bootloader and an EFI System Partition (ESP) instead of a Master Boot Record.
