Same thing here, stopped playing because there is no point. I also opened a ticket and sent debug file. You should also do the same, with more inputs maybe the solution will come faster :)

I am getting the same thing in my game. It's totally frustrating. I also took screenshots, have a save and a debug txt file. I couldn't find anything of note in log file. I could upload all of this if it's needed but i don't have dropbox or something like that where I can upload stuff.
