Orange crashes when trying to close it during freeze:

I am unsure whether this was already fixed, but I got the below crash on the latest bundle (3.32.0). It happened when Orange warned me that some add-ons are missing (when opening a saved workflow) and I opted for installing the missing add-ons. Orange froze and when I was trying to close it, the crash appeared.

Traceback (most recent call last):
  File "/Applications/Orange3.app/Contents/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/orangewidget/workflow/mainwindow.py", line 230, in closeEvent

I also saw this one a few times. I do not think it has been fixed yet.
