Ok, after some minutes of checking my .ved from Simon, he was able to solve my problem with the crash.
My weird waysystems was the trigger for the crash.
I build my waysystem with overlapping borders, so the character can walk around some objects. But this overlapping borders causes the crash, because they implemented some new gamecontroller support and this want not work with my sort of building the wayborder
The better way to make some not walkable spot is to do a point outside the system und put this one as a polygon to the spot.
And again, thanks for the quick response and the help for a solution.
The picture shows my weird wrong way to do this not walkable spots . . .
