When trying to upload my build to steam they get a problem I dont get

So steam responds with this whenever I submit my build:

Failure:
Your build has failed our review because it fails to launch on Windows through the Steam client. The app also crashes when manually launched by clicking the executable file in the install directory.

After launching the following error message appears:
“The UE-OneDay_BackClone Game has crashed and will close
Fatal error!”

It’s possible there’s an issue with the game files, but there might also be one or more missing dependencies. This issue likely requires you to upload a new build.
Please test and resolve this launch error issue before submitting for review again.


It works on my brothers and mines computer but when my friend tried it he got this error:

Usually this happens when someone tries to launch the game with only a .exe file and not the rest of the relevant files. Have you tried launching the game on your steam account from your library? Sounds like a build issue on the steam end of things.
