Hi,
The game terminated, when you try to save it (F5 or Save).
The issue is in the "my document".
Windows 11 save link to "my document" in two places in registry, and when you switch the location (for example, move your documents to disk D), you can have this problem, because Windows 11 update only one record in Registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
keys:
{24D89E24-2F19-4534-9DDE-6A6671FBB8FE}
Personal

When both locations will be is the same, the issue will be solved.
