Packaged Project does not open.

My project built with 0 errors, however its just a black screen when I open it. In task manager it is not responding. 1 out of 20 launches the game actually runs. I have the correct map settings and all, and It has worked before. Any ideas on how to fix?

have you verified the engine files?

how do I do that?

in the epic games launcher, click the drop down on your unreal engine install and select verify.

I dont use the launched since I have a source build, where should I do it in that case

in that case i dont know.

how long is it black screening for? 30 seconds? a minute?

indefinetly, the game will only open 1/50 times randomly.

Is there any way that I could see the log of the packaged game?
