Problem with startup Content Manager

[Emill6]

I have this problem with AC/CM that everytime i launch into a race or map or whatever it loads perfectly fine but right when it's about to load in to the start menu it freezes about 1 minute then its working, kinda hard to explain but it's extremely annoying. I tried to uninstall both CM and Assetto corsa, then it fixed but about a week later the same thing happened again, and it's not from downloading a mod, because it came from nowhere.
Anyone knows how to solve this issue?
