Game Crashes When Saving in Windows 11

Platform: GOG, Windows 11

Do you have any mods? No Mods

Please explain the issue is in as much detail as possible:
Upgraded to Windows 11 today. Game starts up fine, and I’m able to load my save game, but as soon as I save, I see a Unity window pop up and then the game client disappears. I was able to find the log file:

Crash!!!
