Ran a DISM scan on my PC, restarted and the game now works. No idea what the issue was, but I'm not complaining.
Thanks to all who suggested fixes.
@RegularEggKing It's possible that the permissions for Documents or a subfolder became corrupted; the new account has its own fresh Documents directory. It's also possible that OneDrive is interfering; you didn't sync your new account with OneDrive. If you ever tried to move the location of Documents in your old account, it's possible that something went wrong with that move, but again it would only affect the one account. There are probably other possibilities I'm not thinking of as well.
I'm happy to try to keep troubleshooting this issue with you if you want. The first step would be to disable OneDrive in your main account, that is if you use it. If the game works, you can reenable OneDrive and change its settings.
If that doesn't help, or you don't use OneDrive, please let me know whether you've ever tried to move the Documents directory.
