It is from the advanced vehicle starter project with minimal changes. It has also happend to different projects i have made from the same template (4-6 times) And now i cant open the project without it failing.
I appreciate all the help. And thanks in advance. 
I think it can be something with my graphic drivers? I also run windows 10, this problem also happens in windows 8.1 and i decided to do a clean install of windows 10. This did not help.
