A lot of crashing...

so, whenever I play for a while, if too many entities come into my render distance I crash. This normally happens whenever I am playing on a server, because lots of npc's and players are being generated at a time, first few times of entity loading is completely fine, my nintendo switch keeps running, but if many mobs load at a very rapid pace and the game has been running for a while, my game crashes, saying "The software was closed because an error occurred." It may just be my switch having a bug with the built in crash recovery, but nintendo recently updated the switch and I don't think that the crash-recovery is the problem, it may just be some rendering issue that causes my game to crash. If you guys could fix this, that would mean a lot, because my game crashes very frequently when I am playing with my friends and it takes 30 minutes to get back on.
