So acutally, this wasn't my PC problem, it has something to do with zombie bloodmoon spawning
Game was crashing because i made raid base into cliff, so when zombies spawned, some of them spawned on cliff and that made my game crash
I was lucky scrolling trough reddit comments because i found someone that did same as me, he built his raid base into cliff and he had crashes too, he moved his base away from cliff and crashes stopped
So i moved my raid base far away from cliff and now it works perfectly!
