Exception Dialog box appears when Opening POE 2

I played POE 2 this morning. Quit the game, decided to go back in to check something, and then got the following error message:


Exception

Metadata/UI/PreGameState/Login/Queue.ui(13, 15): error: Picture "Art/2Dart/UIImages?common?background1" is not defined. Metadata/UI/PregameState/Login/Queue.ui(34, 25): error Control: "login_queue_frame.message_label" doesn't exist.


I have gotten this error message before thought it was a one off. If I repair the steam game cache, the game works, but what if that fails at some point?
