Sounds like the issue began before that; that earlier fix only applied to mission 15 onwards, so not sure how you got to that point not being able to see the screen after mission 3 as you said earlier, but clearly this is still a persistent problem we’ll need to thoroughly track down.
In the meantime: please see the new updated v1_HOTFIX_BlackScreen file upload – this is a universal and cheap temporary fix, but should work regardless of where you are and/or what you’re doing.
It works by fading back in the screen after 5-seconds of the player character doing nothing, i.e. no movement/button presses etc. That should allow you to continue the game from any point a black screen occurs as the game is still running in the background. Hope this finally helps!
Updating this in the development blog too as it is persistent amongst players, thanks.
