Game Publishing error

My studio has been doing this for about a month now. It doesn’t save randomly. It saved just fine until I imported my cars then it started failing. There are no viruses in the car as they are my own and I have tons of them in the game already. Removing them seems to publish them just fine but re-adding them it fails.

Any Ideas as to why? There are pictures to help understand what I mean.

I’ve tried:
Updating Studi0
Reinstalling studio
Resetting my internet
Reducing game size


Maybe it could be that there are too many parts in the game?

I need to redo the post I mean that I can function properly in studio and do normal things like add to the map and script big things but I can’t add cars that’s it, so no its not the part count.
