I have not heard that there is a general problem with windows 11.Windows 11 is your problem. The version of Python (2.7) used with the Renpy shipped with HI does not support Windows 11. For Windows 11 a least Python 3.x is required, but switching from Python 2 to Python 3 is a major undertaking that Darkhound will not take on ligthly. I know, I have professionally seen major software vendors take 1,5 years to convert from Python 2 to Python 3. With boatloads of issues in between.
And I cannot really believe that is the case, because otherwise there would be a ton of reported bugs by now.
Windows 11 still has trouble with hardware support and drivers though.
I cannot just upgrade the Python version, because it's an integrated part of Ren'py. And switching to a new Ren'py version will cause a lot of trouble and I have no idea how much time it would take to fix everything. For the time being it's not an option.
zapallbugs - Do you have a viable source that states that Python 2.7 does not work with windows 11?
I'm curious, does anyone else run the game on win11? With or without problems?
