US forum is way more active both player/dev based, better check there for issues like this.
Anyways, here is the solution to fix this issue ( many reported that their issue have been fixed, same goes for me )
Bnet launcher > ow2 game settings (on launcher) > additional command line > --tank_WorkerThreadCount 2
You can change this to 4 if its still freezing. But this fixed my issue and many others. Only downside is, sometimes fps drops kicks in but gotta be okay with it till blizz fixes the issue officially. Hope it helps!
