Assetto Corsa Error Message With Barnds Hatch (I didn't do anything with the track)

[Mr.MH2]

Hello everyone,
I wanted to make a race in Brands Hatch with mods, but I got this message, after that I tried to make practice with a Kunos car, but same....and after this I tried with enabled CSP..the track has been loaded but unusually.....(you can see in picture)
Can somebody help me?
It's caused by a mod?
I will be grateful...
Thank you very much
(And sorry for my bad English)

And I got this message ( It writes about camera facing or what):

Run an integrity check with steam and try again.

Thank you very I tried multiple times but sadly still same.... thinking another thing, I often compress the files (I don't know it's important)

 

[Pfalzdriver]

No, compression isnt the problem, I've my game compressed too.

Did you try with a vanilla car?

Or delete the folder "content\tracks\ks_brands_hatch\" manually and run an integrity check again. Maybe something is in there, which shouldnt be there.
