One other detail: I installed SupCom Forged Alliance first, then at some later point I uninstalled OneDrive, and then recently I installed FAF Client, so OneDrive was long gone but it seems like SupCom Forged Alliance used the OneDrive path for its files, and even when OneDrive was uninstalled, the file paths it used were still there, probably because Win11 didn't move all the stuff and delete those folders, it just kept a shortcut to those folders, or redirected to them. My desktop is still :\Users\me\OneDrive\Desktop. Perhaps this issue is caused by file permissions/properties trouble or shenanigans from installing SupCom Forged Alliance using folders that OneDrive needs to access.
