Blender file not importing correctly

I have created this car in blender:

but when I save the .blend file into my assets folder it looks like this:

The colors are not displaying properly and it has added all of these shapes that shouldn’t be there. Any ideas would be much appreciated!

Apply scale and rotation for objects in blender (CTRL+A>…) It’s also recomented to use one material so just bake them into one texture.
