Hi, good day!
That’s a really tough situation especially since it broke right after an update. You’ve already done a lot of the right troubleshooting. This likely means Windows is stuck in a failed update state.
The best thing to do in this situation is to perform a Clean Install of Windows 11 However, you will need to find another working Windows computer from a family member or friend near you to create the Windows 11 USB Installation media.
Find another working computer then download the Media Creation tool (Click Download tool now). Use the tool to "Create installation media (USB flash drive at least 8GB in size) to install Windows 11". Instructions inside the link.
Note: Please make sure to uncheck the "Use the recommended options for this PC" box. Please check the link below for more details.
If you want to retrieve your important files, Insert the USB Installation media into your computer. Please change the boot order in the Bios Settings. Boot your PC from the Installation Media you created.
Click Repair your computer > Troubleshoot > Command prompt
Type: notepad.exe
Press Enter
Click File, then Open
This will open a Mini-Explorer that you can use to find folders or individual files that need to backup, right click the files to Send to USB flash drive.
