Black Screen and Game Crashes

My son has a Kindle Fire, operating Fire OS 5.3.1.0 and MCPE 15.2.1. Up until this morning all was working fine. This morning he went to log into MCPE and the screen goes black and then the game crashes before even getting to the log in screen. We have three other Kindle Fires, all operating the same OS and MCPE. There is only a problem with the one tablet.
