Nevermind i fixed it :)

Every time i scroll past a certain card i accidentally messed up in browse i get an error box that wont go away. it wont let me quit anki the box just keeps popping up and it wont let me press command+Q even if i do it right as i close the error boxes

i have no idea how to fix, it says to go to tools>check database but anki wont let me click anything or scroll anywhere or do anything but close the box just for it to immediately pop up again

this is what the box says:
"An error occurred. Please use Tools > Check Database to see if that fixes the problem.
