Aha ... The "black screen" error occurs when launching the mod if the screen resolution is set to 1280x720 or 1024x768 or less in the System.
If the screen resolution is set to 1280x768 or 1600x900 or 1920x1080 in the System, then there is no error.
It doesn't matter what resolution you set in the Game Menu.

In the "Display" mod settings, the "default" field of view is FOV = 75.
This is a low value.
The official game has a default FOV = 95
