The Grass GUI issue is due to to wxPython4 with Python 3.9 which segfaults.

This issue is fixed in wxPython4-4.1.1 which requires wxWidgets 3.1, but I assume it's not desirable to update to the 3.1 branch since it isn't stable like the current 3.0 series. I tried with a backported [patch](https://github.com/wxWidgets/Phoenix/commit/5cace47aaece3cc4f2e6ea97d7fd5bb8ed316ac9) to wxPython4 but still had the same issue.
