Roads are missing in the nevada interstate map

So, when I was gonna play on nevada interstate this happended! The roads have appeared to be missing. I tried clearing cache and reinstalling it but it still looks like this. Plz tell how to fix it!

The mod was last updated in 2019. Probably due to being old somethings have changed in the game, which resulted in the roads disappearing.

 

I'm making a beamng movie, I have created a scene but i can't since the roads are missing. I'll make a new scene or save it
