I faced this problem in venv,without venv no problem,and nothing to do with py310 or py311

I also get the same error after building with pyinstaller: clr-loader 0.2.5 pythonnet 3.0.1 python 3.10.10

I have no idea what the problem is, since it works on my win11 machine, but won’t on another and I did not install any additional .NET dependencies.

Is there a workaround? Or do you need more info? I see this issue is closed, but seems to be an ongoing problem.
