Hi !
Nobody met the same issue ?

I will try to update the engine to the latest version, and see if the problem is still here.

Hi mikee3556,

A couple of questions about how you are packaging and how you are deploying to your Win10 laptop.

Make sure you are packaging for Windows 64
When you package for Windows 64, be sure to include the entire folder containing the executable -not just the .exe file. The executable references other files in the containing folder.

If these steps do not resolve the issue, please describe in detail how you are packaging and deploying your project, including your package settings in your Project Settings: Do a full rebuild, do not use chunks, pak or no pak files optional.

Also, be sure to brush up on the following documentation: Releasing Your Project

-.

Hi,

Thanks for your answer.
Actually, I have not followed the Preparing Unreal Engine Projects for Release | Unreal Engine 5.2 Documentation step,
but this one: Packaging Unreal Engine Projects | Unreal Engine 5.2 Documentation
And then I launch the .exe directly Inside the WindowsNoEditor Folder (“MyGame”.exe)

However, I succed to skip the black screen issues I had. The problem was the startup movie.
For the test, I tried to use the animated UE4 logo, so I converted it from .mov to .mp4, and I guess the format was not the expected one.
So, I converted again the file, but this time in H.264, 720p and now, it works !

Moreover, the last version 4.14 not solved the problem, actually, I could not drag and drop files anymore, movie import does not result in a media player import, but another kind of file and also, the quality of video droped down a lot.
So, I just update the 4.12.2 to the 4.12.5.
