I built my 2d game to mobile and at first it works correctly. But i play the game for a bit on my android phone and then I turn it off and after i try to turn it on again, just after it goes past the splash screen to the first scene, it crashes and keeps crashing from that point at the exact same place continuously until i clear the cache of the game in which it loads correctly again, only to crash again the next time i load it.
I also tested it on my brother’s phone and it also had the exact same error and on his own device, clearing the cache doesn’t make it work again at all, just keeps crashing. I have no idea how to fix it.
For more information, I switched the scripting backend from il2cpp to mono for quick testing on my phone as it builds my game in a little over 10 mins on average on mono instead of the 45 to 1 hour build time with il2cpp. I connected my device with unity’s android logcat and whenever the crash happens, i get this series of crash messages before the final fatal crash report:
