Hi, my anki keeps on crashing when I try to study a certain deck. I have removed add ons and clicked on Tool-\> Database which removed about 40 cards. I added these cards back to the deck (which may have been a bad idea in hindsight) and now the deck is crashing again. I have repeated the same steps yet now no cards are being removed so I’m feeling a bit stuck. Below is the error message. If anyone can help, I’ll be super grateful !!

If you use the More button and choose Forget Card, it will likely resolve the problem with the card.
