After updating to the latest version I noticed that there was a new app or game at the top of the game drawer saying "SetupIntro". After I got to the end of the crank animation, It suddenly got a failed assertion:
assert( sys->device!=NULL ) failed:
core/playdate.c:17 in completeGame
It seems to happen after the "Playdate" ending animation, regardless of weather I have the crank opened or closed.
The home button seemed unresponsive and after a couple minutes I got a low battery alert after I took that picture but when I reconnected it said 10% battery left. The issue happens either on battery or while charging.
