Several Windows 11 21H2 computers will not upgrade to 23H2, error code 0xC1900101

We have about 20 computers under management that will not upgrade their build to 22H2 or 23H2. They consistently produce the error code 0xC1900101. This is a failing of the "SAFE_OS" mode where it boots into a Windows PE instance for the purpose of finishing the update, but it apparently is crashing in that step. I've tried various methods of performing the update. We've used the ISO inside of Windows, Windows Upgrade Assistant, and booting the computer off the ISO and none of them have helped us move forward. I'd prefer not to wipe and reload these computers. Has anyone else run into this?

Thanks,

Andrew

Your system is fully up-to-date. What else you're looking for?

//I'm going to just assume 23H2 doesn't actually exist yet and count it as vaporware.//

No, it's not.
