On Windows 11, error messages say:
Platform: Windows 10
Debug info says:
Platform: Windows-10-10.0.22631
So, Anki doesn’t distinguish between Win 10 and 11.
Distinguishing between Win 10 and 11 is easy and doing this in Anki may make support easier.
The Windows 11 version is reported as “10.0” with a build number >= 22000.

Basically, unless the application was updated to know about Windows 11, it’s going to think it’s Windows 10.
