To follow up, updating `[config]/core/interpreter_[os].cfg` to point to Shotgun’s python 3 path instead of Python 2 will ensure the app will run in python 3. For example, on windows, change `C:\Program Files\Shotgun\Python\python.exe` to `C:\Program Files\Shotgun\Python3\python.exe` in the file `interpreter_Windows.cfg`.

It looks like those interpreter files will be unnecessary after Nov 1st, 2022, when SG Desktop is updated to use python 3.9 by default: [IMPORTANT NOTICE - Upcoming removal of Python 2.7 and 3.7 interpreter in ShotGrid Desktop](https://community.shotgridsoftware.com/t/important-notice-upcoming-removal-of-python-2-7-and-3-7-interpreter-in-shotgrid-desktop/15168)
