MTG Arena crashed, and when I opened it again, my avatar changed and I couldn't use emotes
When I had just clicked on "Play" and was waiting for an opponent, MTG Arena crashed. When I opened it again, my avatar had changed and I couldn't use emotes (clicking on my avatar during a game did nothing). When I restarted MTG Arena one more time, my avatar was back to what it was before.
The same happened to me right now.
