By setup you mean my computer setup?

The in-world setup used to crash the game.

Can you take a screenshot of your setup?

Also tested again to check if it still crashes and it does.

Aha, it is assumed that there is a chest on top of the MRS. There's no nullcheck in place to catch a missing tile entity there.
