Reinstalling Steam solved my freezing during game startup. But still have same problem as Subject42. Freeze sometimes after 5min, sometimes after 60 min. ...

I have also issues with frezeing. Sometimes freeze while starting the game (after Bohemia Interactive), sometimes when message about Early access shows, randomly in menu or in the world. When I try to kill it by using Task manager I fail because a can't click anywhere with my mouse so only solution ofr me is logout from windows. It started few day ago. Now I can't play at all :(
