Since upgrading from 4.8 to 4.9 we’ve found that when we run the game it gets stuck at a black screen once our startup movie finishes until we click somewhere in the window. We have one movie at startup with “Wait for Movies to Complete” on and “Movies Are Skippable” off.
I was able to repro this by creating a new blank project and adding our startup movie to it using the same settings.
This is fortunately a known and reported issue. You can find the post that generated the report below. I am going to mark this post as duplicate and resolved for tracking purposes. If you have any other questions in regards to this issue, please respond on the answerhub post below.
