Bug in the first campain misson in War for the Overworld - The Under games Expansion

Hello guys,

I have a problem in the first misson of WftO - The Under games Expansion:

If I start the first Mission, the sequence when mendechaus is explaining the Nether Shrines could not be skip with the space key. And there is no voice of mendechaus, he stops reading the undertitle of Nether Shrines. There is no way to get on with the Mission, it stucks in the camera Rotation around the the nether shrines. If I want to get back to the Desktop with the fast button of the menu of WtfO the game does not Response, I have to quit with Task Manager.

My Hardware:

Intel I7 8700

Nividia 1060 GTX

Win 10 home

16 gb rams

I Play the game in Ultra Settings.

Thank you for your time I hope you can solve the Problem.
