Tracks KS EDITOR CRASH, HELP

[Villalbaa_27]

good morning everyone, I have been making a circuit for a few days trying to do it inside a room with blender, but now that I have started exporting the fbx to use it in sk editor, it keeps crashing, I have tried a thousand things and it still doesn't work, The environment is done, and the track is half done to test.
The texture there is for the entire environment is a random one to test if it worked or not.

I hope someone can help me because it's been a whole day and I can't import it into sk editor

Main thing that'll make it crash is objects that are too complicated (actual limit hit is 65535 vertices, but this count will often be higher than a 3d modeling software shows. To be safe aim for 20k quads or maybe less) Might want to check your object names are letters, numbers and underscores or periods too.
