Black screen on saving key binds

[Sporg]

As title, I had problems on saving key binds in fresh NTTR.

DCS turned black screen.

 

A friend of mine had same problem, but he said that key could be bound when in mission, and then it worked.

 

I copied my config files over from release, and that worked too.

 

Afterwards I removed them again and put the original configs back.

Here I changed only one keyboard bind, and that worked also.
