After editing a card, I click close on the edit pane and the program crashes. I reproduced this 4 more times. Progress of all recently done cards is lost. This bug was reproduced even with all add-ons disabled.
FIX: The problem may have been with the Big Sur (Mac’s most recent os update). After restarting my computer, the problem resolved itself.
Edit: added the link
Edit: added the sentence about add-ons
Edit: title, deleted report link, and added last sentence.
