Fatal Error with Merge Notetypes

Hello! I have been having this issue for months since the new update. Whenever I try to import a deck, if I click merge notetypes, Anki crashes and I get the errors seen below. I need to merge notetypes or else many cards will not import usually. Anyone know how to fix this?

Try #4 (Check Database) and #2 (Disable add-ons) from the Troubleshooting Checklist.


Please also confirm the issue exists with the latest Anki version, which was just released.
