Error in Aplication on PS4

I have a world with another friends on PS4, but there is a time when the game closes and says: there was an error in the application. When this error occurs to me (I'm the owner of the server) I lose mobs with or without nametag. I cannot identify what is causing this erros, because they are at random times. Has occurred more often after the Nether Update (1.16.0 and 1.16.1)

 

I'm waiting for the answer

Thanks :3
