Duels will not let me make a demonhunter deck

so i was playing with the duels and click demon hunter and got to the part where it says build deck and click the build deck button and it just flipped and sat there. restarting my game did nothing it just tells me to resume and then sit there on the flipped button forever. the game also will not let me retire the deck to start a new one it is just stuck on the demon hunter building part

as a note i do not have demon hunter unlocked as a class to play as but do have plenty of demon hunter cards.

It’s worth noting that the prologue spoken of here is the “Ashes of Outland” prologue. For anyone (like myself) who’s been away from Hearthstone for a while.
