Hi, i am having some similar problem. I have a deck in my anki and i downloaded another anki file of 3gb, however whwn i open that file in anki , anki opens up and then closes. I cant see any card or deck added other than the ones i already have.
Checked database but nothing happened.
I can remove previous deck if thats causing problems but i dont know how to do that
