Black screen and crash since todays update

[PsyBlade]

Yesterday the game was working fine and today it first shows a black screen and finally crashes.
Besides the game I to not recall any changes in between

Console output seem mostly insignificant besides the following:

../common/pipes.cpp (770) : Assertion Failed: fatal stalled cross-thread pipe
../common/pipes.cpp (770) : Fatal assert failed: ../common/pipes.cpp, line 770. Application exiting.

Let me know if you need further info. Some dumps seem to have been be uploaded.
