The Game Freezes

Hello…
I can not play the game, it freezes.
I have.
I5 6600 16GB Ram and a GTX1660 Ti, before the last two updates it still worked, because I still had a GTX 770, now I have specially bought the GTX 1660 Ti but nothing has changed.
The game just freezes, repoort is out.
I’m from Germany and use Google translated.
Please help…
