One of my decks has stopped showing reviews

In fact I’m using Anki for more than three years every day but suddenly one of my decks with 1100 cards has stopped showing cards. If i use custom study(review ahead-1 day) it will have 659 cards for review. But unless doing that there is no scheduled cards.
I’ve had problem with that deck for more than one month

Your cards are currently in the Custom Study Session deck. Deleting the deck will return them.
