macOS 12.3 does not include Python 2 anymore, so it needs to be installed manually. Did you update from 12.2 to 12.3.1 directly? In that case, this dialog window is as expected. Install Python 2 (if you don’t have it installed already) and the pyobjc module as described here:
If you already did that when updating to 12.3 and now get the same dialog at 12.3.1, there might be a different issue.

Thanks, I updated from 12.2 to 12.3.1 directly.
I installed Python 2 and pyobjc as described in that other thread, but now all the plugins crash when starting Glyphs and none of my scripts do anything. I’ve tried reinstalling the plugins but that didn’t help.
