Can't sideboard after reloading into a game, best of 3 ranked standard.

Game crashed during round one on Android for no reason. Normally I'm able to sideboard fine, I did that one game earlier with no issues. This game I'm unable to choose sideboard cards to switch in. I can remove cards from deck just fine, which leaves an unplayable deck (required a restart).

Screenshots showing what happens when I tap a card (nothing).
