Hey everyone…

i have package my project to launch, but when steam is open and trying to launch the game its crash and give me this error. i have seach for long time, and can’t find why. i have looking in package settings, files, but nothing is causing this error. If i launch game by Editor (rightclick on project file) it works with steam, and no errors at all… im stuck on this

nobody help here?

Well… i got it to work. Advanced session steam was causing the error.

What do you mean by Advanced Session Steam?
I’m having the same issue here

Hey,

So I had the exact same issue, down to the letter. 0xfffffff and weird callstacks about slate or whatever.

If your problem is exactly the following :

You can host and join a game without issue in the editor in standalone mode
You get a fatal error when you package the game in dev and debug mode
You don’t get the steam Overlay if you use shipping

The answer is simple, yet it took me 10 hours to find it, thats’w why i’m sharing now : All you have to do is add the steam api 64 dll in MyProject/Binaries/Win64
