Hi, could you also share the mods that you are running together with?

hi! sure. there are a lot of them. do you need the full list?

Probably would need all of those that interfere with map generation and especially, based on the error message, those that work with trees.
QoL mods or mods that only add buildings, recipes or equipment could be skipped.

i've switched on and off some and looks like it's https://mods.factorio.com/mod/alien-biomes
