No errors but scripts not loading anymore


my problem is, that the clothes, cars and map script on my server are correctly starting up but
in-game I can’t see the maps, etc.
So they start but they are not avaiable in-game.
In the console is no info or something. No errors, etc.
I already tried to some things like take another FiveM-Server-Build. It doesn’t helped.
PS: Only one single import car works. I don’t know why… Only that one can be spawned. Anything else not.
