Everything was working just fine,  then I started to build railroad, first problem was when railroad needed to turn right it's keep sending my minecraft backwards and I don't know why. I tried everything but nothing works, then a pillager patrol comes and one of pillager was stuck in scaffolding in the water.

Then I tried to restart my game and when I did this I joined my world again and game just chrashes.

P.S. sorry for my bad English, I hope you will understand this.
