I have the same problem. Environments were created with Anaconda. I can switch environments in VS and open the “Add Environment” dialog, but clicking “Manage packages for this environment” or “Open the Python Environments” results in a crash.

This is on VS 2019 16.7. It's due to a detected Python 3.9 environment that we can't parse into the PythonLanguageVersion enum since 3.9 was not a member of that enum back then.

It has been added in 16.8 so this particular environment/scenario should no longer lead to a crash.

We should still fix the calling code to not crash on InvalidOperationException since that will still happen on future unknown versions of Python.
