Installing Python 3.11 breaks Python 3 API

Installing Python 3.11+ on Windows causes Resolve to throw "Python 3 not found" every time the console is opened, regardless of installed compatible versions (3.6 through 3.10).

This could be due to Python 3.11 being on your windows PATH or PYTHONPATH environment variables and thus forcing the loading of non-compatible libraries of 3.11 into the older versions.

Could you check your system environment variables whether they have anything Python 3.11 related in a key named PATH or PYTHONPATH - if so, could you try again with those values removed from those environment variables?

Also, only Resolve V18 supports python 3.7 and above.
If you are on V18 it is likely an env path issue as mentioned.
