consider reporting on the discord with your phone's model, it might be not powerful enough (a memory issue?) or maybe overheats
i've been elsewhere. anyway, renpy did screw up with a recent update, it seems some phones can't run the game for now, it seems to happen more with newer phones (also the 1 tB SD or not overheating don't assure the phone has the necessary specs, but we honestly didn't find a definitive answer on the discord for now, try another device if possible)
