Anki does not show my decks

I guess the issue is caused by having too many decks or large deck trees, and not too many notes. There is no set limit for the number of decks/notes you can have as far as I know. Additionally, the issue should be fixed in the coming release (2.1.50).

10000 notes should not cause problems. I have 24x as many notes and never had this issue.
