At first it switches to a black screen then CTD, log had no error of anything.
I moved game to C:\RimWorld\ now I get to see the menu for a split second and hear music until an other CTD without error.
Damn, This one time I got a lot of stuff in the log, but now it's again saying nothing...
It shows normal loading until
(Filename: C:/BuildAgent/work/d3d49558e4d408f4/artifacts/StandalonePlayerGenerated/UnityEngineDebug.cpp Line: 53)
Platform assembly: C:\RimWorld\RimWorld462Win_Data\Managed\System.Xml.dll (this message is harmless)
Platform assembly: C:\RimWorld\RimWorld462Win_Data\Managed\System.Xml.Linq.dll (this message is harmless)
Then nothing
which version?
I tried Alpha4c through f and my friend still had his archive of 3f and they all do it...
MSI afterburner's overlay was the culprit, it's solved now
