PackagingResults:Error: Error Unknown Error

I just recently updated my project to 4.12 from 4.9, and decided to run a test package to see if it would work, and it did not.
The error log isn’t really helping me since all I am getting is an “unknown error”.

I am pasting the log file below, thanks!

Hey Prestonator,

Could you please provide the full output log from your project’s Saved->Logs folder after you attempt to package again?

Are you able to package a clean, blank project?

Hey Prestonator,

After further investigation, it looks like you’re trying to upgrade Shooter Game from 4.9 to 4.12, which can definitely cause some issues as far as differences in the code go. I’d recommend downloading Shooter Game strictly for 4.12 and working in that instead, that way you don’t have to worry about making the necessary code changes. If you don’t want to work in a 4.12 version, then downloading the 4.12 version and comparing the code to your 4.9 version will allow you to ensure you’re making all of the right changes.

Let me know if that helps.

Have a great day
