TypeError: '>' not supported between instances of 'NoneType' and 'sys.version_info'

[kistlin]

I tried to use it with Python 3.11 and get an error now. Maybe it's package version issues.
It doesn't work on Linux with fixed package versions I used previously nor with the latest package versions. On macOS I had similar issues, but an older Python version and fixed package versions still worked.

Exception has occurred: TypeError       (note: full exception trace is shown but execution is paused at: _run_module_as_main)
