Stuck in Recovery Environment after Windows 11 update

Trying to help my wife with an issue she’s having. After updating to Windows 11 through the app on her Windows 10 installation, we’re stuck on the Recovery Environment/Advanced Options Startup screen, and haven’t found a way past it or understood what the issue is.

We can access the BIOS menu and the command prompt, but we can’t access safe mode. Running Startup Repair gives a prompt that it couldn’t repair, and cites a log file that I can’t seem to navigate to in the command line. Clicking the button to “exit and continue to Windows 10” just restarts the computer (should I be bothered that it says Windows 10?).

Prior to the update, the only compatibility issue was the requirement to enable TPM 2.0, which we did in the BIOS menu. I’ve tried enabling Safe Boot but that didn’t change anything. The BIOS is up to date. The motherboard is a Gigabyte B450 Aorus Pro.

Thanks in advance!
