The build number 22631.2506 implies the device has been upgraded to 23H2 already.

Here are the version/build numbers for Windows 11.

• 22000.xxx is 21H2

No, it's not.

Windows 11 23H2 upgrade broke File Explorer, it will not run

Good news!

Problem seems to be fixed by 2023-11 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5032190) update released 11/14 that I installed on 11/15. In the Knowledge Base notes is the following under File Explorer:

• This update addresses an issue that stops File Explorer from opening.
  

It worked for me, no longer have any problems, no need to re-install (somehow I couldn't roll back 23H2 update and had no recovery point before that time).
