CTD/Freezing

Guys, every time I try to play the game some of these things happen: crashing to desktop during a race or freezing in menus, for example changing a car.

I already tried these solutions: https://forums.forza.net/turn10_postst110022_-ANSWERED--Forza-7-crashes-to-desktop-on-launch.aspx

I also tried to reinstall the game, reinstall graphic card drivers and update Windows.

My config: Windows 10 1803 (1709 also didn’t work)
8GB RAM
i5 2400
GTX 750 2GB

The CTD happens more often in singleplayer, but in multiplayer too. When I complete a race and the game is loading the next track, the usage of memory RAM increases and then the game/PC freezes. The only way is restart the PC by the power button.

Would anyone else have a solution?
