My wife's computer started asking for her BitLocker code on boot and even during sleep mode. To resolve this, we disabled BitLocker by going to Settings > Privacy & Security > Device Encryption and turning it off. After decryption, we restarted the computer but only reached the Windows 11 Setup screen.
We haven't backed up the files, and really want to avoid a full reinstall. The motherboard is an ASRock, and we've already tried enabling Secure Boot and TPM, but nothing seems to help. Has anyone experienced this before, and do you have any tips to recover the Windows 11 OS without losing data?

If nothing else works, sometimes reinstalling Windows is the quickest fix. You can opt to keep your files, depending on the installation options.
If you haven't already, you can try creating a live Linux USB drive from another computer. Booting from that can let you check if her files are accessible without doing a full Windows reinstall. Also, make sure the boot order in your BIOS is set correctly.
You might want to check your BIOS settings. When you disabled BitLocker, it could have changed the SATA mode setting. Switching it to AHCI might help you get past the boot screen.
What do you see when you start the computer? Just the ASRock boot screen or does it go straight to the Windows 11 Setup menu? That can help narrow down the issue.
If you plan to use BitLocker again, once it's finished encrypting, you can resync the key to the TPM with these commands in an elevated command prompt:
1. Manage-bde -protectors -delete c: -type TPM
2. Manage-bde -protectors -add c: -tpm
The first command clears the TPM, and the second adds the new key.
