Error Unknown Cook Failure When Packaging?

Hi Guys,
When i package my game, on the output log it shows a error cooking failure. I have previously packaged my game before this and all was fine. Since doing that i have messed around with adding an additional level and another FirstPersonCharacter to change the dynamics of the gameplay. I see there is a error with the additional FirstPersonCharacter, but how do i approach the problem? Here is the output log i am getting. Can anyone help? I’m quite new to Unreal, so any helped will be amazing!

Hey Idle K,

In order to effectively assist you, I am going to need a bit more information.

  1. What platform are you packaging for, and what are the packaging settings you have applied?
  2. Could you provide me with your full log from the failed package attempt so I can look through it in greater detail?
  3. If you are able to reproduce this in a blank project using simple repro steps, and provide me with those steps I will try to get the issue to occur on my end as well.

Let me know if you have further questions or need additional assistance.

Cheers,
