I have already gone through all of the items on the trouble shooting checklist and have had no success. I have attached my error code below for the issue I am experiencing. I checked the database, which says that 516 cards are deleted. My hope is to recover these and avoid the issue, figure out what it is to avoid it in the future. I really am not sure where the issue is stemming from. I even tried to downgrade my anki app to go back to how it was before but even this didn’t help.
