It appears just when I click the empyrion-icon I got this Error after the update from today. Yesterday all runs fine. I verified the local data, cleaned the cache. There is no log report for this error.
I found a Steam log from the GameOverlayRenderer.dll talking about a hooking error. I hope this will help. My processor: Intel i5-4590 3.3 GHz 8GB RAM
Now the Game runs again, I don't know why. I had some reboots till now, and played an other Steam-Game.
