Can't Repair Wow retail client

I was playing Wow this morning 30/11/2020 did the flappy bird world quest in bastion game started to lag out very hard i got disconnected from the game then i could not log back in. I kept getting stuck in the log in screen then my charachters dissapeared from my server list and it says i was a new account, then i attempted to run a repair scan the which told me the game was now damaged and now i can no longer log in or play and whenever i repair the game it says it cannot update with an error. I tried everything i could find on the suggestions page including disabling other security programs and such and nothing would work. I have now uninstalled the game and am having to re-install it from scratch just thought i would let you know in case there is a bug in the game?
