There are a lot of blackscreen / freeze crashes on servertravel. In our latest playtest 1 of 6 players would crash out pretty much on every servertravel. In 4.16 it would crash with some error message, but since 4.17 it just freezes.

And one client was receiving a lot of D3D11 crashes, probably unrelated and they happend during gameplay.
Edit: I’ve run the game with VS debugger now to look at what happens when it freezes during servertravel, it does not trigger a break or anything, but pausing at the freeze stops here in ThreadingBase.cpp:

and it seems to just wait indefinitely and the engine is completely idle.
