Cannot play as anyone due to a bug in the deck system

Hello. I have stopped playing this game for a while and decided to come back to it. However, there are some issues that stop me from playing as anyone other than Demon Hunter.

1: All my decks are ruined because the cards are locked out of “Apprenticeship”

2:When the game wants to auto-make a deck and I say yes: it either says

“2 cards are locked from apprenticeship. Would you like to complete your deck?”

(If I click yes again, it just repeats itself.)

Or it won’t say anything and kick me to the deck overview.

3: When I create a deck manually it won’t save and it will put back the OG unusable cards.

(Also Demon Hunter works fine)

Any help?
