QGIS 3.20 segfault (OSX Only)

[MattReimer]

Hey there.

I just upgraded to QGIS 3.20 and I'm getting a segfault when I try to click the debugvs button. I've tried re-installing the plugin and reinstalling ptvsd using pip but I just can't get it to work.

The plugin seems to still work fine in the LTS version so I'm assuming this is just a problem with QGIS 3.20

Sorry for this sparse bug report but it doesn't seem to give me any good errors. I did notice the terminal popped up when QGIS died and it had the following:

> /Applications/QGIS.app/Contents/MacOS/QGIS ; exit;

I don't think any of this is related to the problem except for that last line of segfault.

This is a really tricky problem to solve. Let me know if there's more I could do to help with repro steps.

EDIT: Seems like this is happening in OSX and not in windows. I'm going to try a fresh reinstall and see if that fixes it.
