Computer Freezes when I load in

The client works fine, and I can get to the loading screen. But after it reaches 100%, I load in for half a second and then it freezes. I cant alt tab, alt f4, or even switch desktops(windows key + tab). The only thing I can do is ctrl alt del, and if I click task manager it just takes me back to the frozen screen. The only thing I can do is log out or force restart. I've tested it in practice tool after it happend in two draft games in a row and it still freezes. Please if someone knows how to fix please share because I dont want to miss out on 10th anniversary rewards.

Edit: I updated my graphic drivers, and it seemed to fix it.
