No idea where's the problem exactly for i have a lot of mods but it is when i enable https://mods.factorio.com/mod/grand-unified-factorio-theory to the pile that it crashes. May have to do with some other involved mod, most likely Yuoki and it's (weird) inserters.

That's looks like quite the huge mod, something in there must be messing things up. Do you know if any part of that mod affects how inserters are placed and picked up?

No

So I tried running that mod with mine and it did not crash with that error. Maybe something somewhere else updated that fixed it. Can you try again to see if it works for you?
