Using UE 5.4, I'm encountering a "Packaging Failed!" error for the first time & I don't understand what's wrong

Hey there,
So I’m currently trying to package a build but I’m getting an unknown error message that I don’t understand (the Log should be at the bottom of this post).

Recently, I wanted to look into reducing the file size of the packaged build so I followed a couple of steps in this video & so far I’ve done (from video start at 0:00 to 4:43):

  • Changed the binary configuration from “Development” to “Shipping”
  • Disabled the “OpenImageDenoise” plugin
  • I’ve confirmed that I “Use Pak File” is checked
  • I’ve also confirmed that “Share Material Shader Code” & “Shared Material Native Libraries” are checked as well
  • Additionally, “Create compressed cooked packages” is checked as well
  • I also have “Exclude editor content when cooking” unchecked
  • And I have “Full Rebuild” unchecked as well

Outside of that video, I’ve also tried:

  • I’m using Windows 10
  • Cooking the project first (which worked without a problem) & then trying to package the game (which FAILED)
  • Set my own Game Icon (but I don’t know how to add the old icon back again)
  • Made sure that I have the latest version of Visual Studio (and added the necessary plugins/modules) based on this tutorial
    • Despite that I get a yellow “PackagingResults: Warning: Visual Studio 2022 compiler is not a preferred version”
  • Gone into “Project Settings → Compiler Version” & set it to “Visual Studio 2022”
  • I’ve deleted “DerivedDataCache”, “Intermediate” & “Saved” folders & tried packaging after restarting the Editor but I get a fail
  • Changed from “Shipping” to “Development” to see if that worked but to no avail

Here’s the “Installation Details” for VS:


Here’s the Log:

I’m reaching a point where I don’t really what else to think of since this is the first time I’m encountering something like this

Any advice is appreciated

That… seem to work?
How did you know that?
