napari: Seg fault on closing napari with framework launch mac

🐛 Bug

We’re currently getting a seg fault when quitting napari after it has been launched with the framework build on mac - likely after #1554. See

(base) czirwc1macos2701:napari nsofroniew$ napari
/Users/nsofroniew/opt/anaconda3/bin/pythonw: line 3: 34762 Segmentation fault: 11  /Users/nsofroniew/opt/anaconda3/python.app/Contents/MacOS/python "$@"

If you do this a couple times in a row you start getting this dialog which blocks launch until it is addressed.

Fixing this and the minimum version issues seems like a critical thing we should do before the 0.3.8 release cc @jni @tlambert03 @Czaki
