Game won't launch in Windows 11

[White Lion]

I'm able to play this game for more than an hour, last year, when I was still using Windows 7. This year I changed my OS to Windows 11. Unfortunately, the game won't launch now. It just show a splash screen. In Windows Task Manager, it only consume several tens of megabytes but 0% CPU. I waited for 5 minutes and nothing happen. The splash screen still show but will not proceed to the game itself.

I'm using Intel X series with 16 cores, 32 GB DDR4 memory, 2x SLI-enabled MSI nVidia GTX 1070 8GB GDDR5. I've tried the following without success:

• Uninstall the game from Steam. Then install again via Steam.
  
• Verify integrity of game files.
  
• Set compatibility to Windows 7 via File properties.

I don't use any mods. Just the vanila version. Is anyone experiencing issues too in Windows 11 ?

Can anyone help ?

It's weird that Windows 11 does not have option for compatibility with Windows 10, but it has an option for compatibility with Windows 8. I selected that option and the game is fully functional again.

Thanks for the input.
