After countless hours of troubleshooting the multibox lockup issue on Windows 11, I finally found the fix.
The fix is simple, but you'll lose ability to use WSL (Windows Subsystem for Linux).
Disable Virtual Machine Platform.
Control Panel -> Programs and Features -> Turn Windows features on or off
Or press window key and search "Turn Windows features on or off"
Uncheck Virtual Machine Platform
Also I would uncheck Windows Hypervisor Platform for good measure.
You'll need to reboot your PC after.
We tried allllllll the things people were recommending but this and downgrading to Windows 10 are the only solutions we have found that actually work.
Good Luck!
P.S. if this works for your, donations are much appreciated!
If do a bit research you will see that the required OS system to run this game is WIN 10 , no where is written Win 10 , 11 , ect...
