WOW Error WOW51900319

I keep getting this error when either attempting to connect to the game or move in game. I’ve tried the steps for disconnects but that has not solved my issue. I would appreciate some help with this issue as I am attempting to try the trial and I can’t even play.

Same here, and in reading other posts appears to be from the 25/02 update. Now I am stuck in a file scanning loop as well when I tried to repair it
