Pycharm ignores new virtual environment after moving existing one or deleting and creating a new one

Question

If I allow PyCharm to create a virtual environment when creating the project, then delete or move the venv folder, it won't let me select a new one. I can go into the Python Interpreter menu in the settings and select an existing one that I created myself (note /brokenInterpreter/oldFolder/venv vs /brokenInterpreter/venv):

But nothing happens when I hit "Ok" in the "Add Python Interpreter" dialog. It simply ignores what I entered. When I exit out, PyCharm still attempts to use the old, non-existant interpreter.

How can I get around this?

I think this is a bug, but I'll document the fix here.

I had to go into the "Show All" menu, and find the old "[invalid]" entry:

Then once that's removed from the list using the - button, I was able to add the new interpreter.
