Minecraft Bedrock on ps4 randomly crashes

Minecraft Bedrock on ps4 randomly crashes and i rarely save my games now. please fix this bug, i have raged because i spent 2 hours on something and it crashed when i clicked save and exit, but that was probably because I threw too many tridents. It also crashed randomly when I was building a city while playing, and I was only placing blocks and there only were 16 entities I could find and no redstone.  It also has a lot of random lag spurts and its getting annoying
