cannot preview in this - unexpected error occurred

i haven't even edited the template file and this happens.

steps: Create visonOS app from template

the immersive view previews and it show 3d objects

Select the realitykit package and Click 'open in reality composer pro'

Change color of material and save

go back to xcode

result: file no longer previews and i get the error in the title

like that's it, how do i edit 3d files?
