This is almost certainly a permissions issue, eg which directories an application is allowed to access. I don't have a Windows 11 system to test on, but I wouldn't be surprised if they changed a bunch of stuff in the name of security.
Do you know of any other 3rd party applications, particularly open source ones with public bug trackers, that have had this kind of issue? If so I could refer to what they did and maybe that'd help us fix this issue.
