Game will constantly crash

game has recently started crashing after roughly 1 to 2 hours of gameplay, unsure what is causing it , I have tried doing everything from clearing caches and checking for corrupted data , even uninstalling and reinstalling,  its not just confined to one world its all my worlds that crash and its even caused a side issue where after booting up the game after roughly 15 minutes of being in game it will say unable to connect to realms or store .
