Game crashed with Assassins

My game frequently crashes, especially when I play as an Assassin. I use a build like Kickca, where I charge attacks with Fists of Fire, Claws of Thunder, Blades of Ice, and Phoenix Strike (all of them together), and I use Dragon Talon as a finishing move. Unfortunately, the game crashes often and I don’t know why. When I go to Blood Raven, Diablo, and now I can’t access the Cow level, although it worked fine before.

The screen freezes without any error and returns me back to Windows. On the launcher, it shows that I’m in the game, and within a few seconds, the “Play” button appears so I can relaunch the game.
What should I do? I played on laptop and desktop PC and same on both.
