Stuck at Battle Pyramid

I have entered the challenge and accidentally auto-saved the game. Now i am stuck in a wall and the game doesn’t kick me out of the challenge. Any idea on what to do? I don’t have any previously saved file to reload

3 Backups are made automatically, each one instanced for when you last saved. Have you literally been iron manning this game, despite the fact that it’s extremely buggy?

Also you can try blacking out by opening the dex nav and fighting the memory chamber trainers (The blue pokeball icon at the right.)
