Stuck in Arena After Win

I’m trying to get through an arena game, just won round 7 but it’s left me idle in the actual game so my only option is to retreat and lose. It hasn’t frozen because I can access the menu but I can’t do anything else, and if I reset the console I can assume the progress will be lost. What should I do?

…and now it happened after levelling up and choosing a mastery.

I haven’t played this game in a while, is it safe to say it’s broken now?

Can you show any screenshots or video? It is hard to tell what is happening right now. I didn’t experienced such thing.

No I just quit out and back in, i’ll just assume the game has general loading problems.
