The Game freezes and crashes

I bought the game a week ago and all i get is freezes and crashes. The game also uses almost 100% of CPU together with 50-80% of gpu. How is this even possible?

At start i was able to play the game for an hour or 2 before it freezes and then crashes without any error code. Now it only takes 10 min before it does.

Running the game as administrator and already tried repairing it within origin.

Please help

my specs:

AMD 5 ryzen 1600x

16gb DDR4 RAM

Nvidia 1080 GTX 8gb
