I keep getting Fatal Error when opening packaged build

So Everything runs smoothly in editor + standalone. The moment I run the packaged build, it doesn’t even start up. I just get a black screen then “fatal error” which then automatically closes the build.

I’ve looked into my crash log and its giving me so many different issues that I didn’t know existed…Files I’ve never touched or even heard of and as a beginner ue4 user, I’m struggling to tackle the problems as some of the mentioned file paths, i :

a. Can’t find
b. Don’t know what to do with them

Appreciate any advice :confused:

Do you use BluePrints or C++ ?
