Unable to deploy my game. Getting warnings and errors regarding uncooked content and dlls

I want to create a build that a player can launch without UE4 or Visual Studio. A standard game release.

I followed this guide: Releasing Your Project | Unreal Engine Documentation

When running the packaged game I get this error:

When I look at the log I see that it failed to open a folder it never made and a bunch of warning about materials and particles being missing. I deleted those assets as I had no need for them anymore. Please review the attached logfile.
[ProjectLauncher.log][2]

What can the issue be? Why am I unable to make a windows 64bit executable with all assets included? Do I have to make an extra installer or something?

Hello NoobsDeScroobs,

I was not able to reproduce your error on our end, I have a few questions for you that will help me narrow down your issue:

  1. Can you reproduce the packing issue with a new Project?
  2. If so could you provide a detailed list of steps so I can reproduce the issue on my end?
  3. Are you packing to a network drive and not your local machine?
  4. Could you provide a screenshot of your settings you used following the guide (Preparing Unreal Engine Projects for Release | Unreal Engine 5.1 Documentation )

Thanks!

I started by redownloading the engine and I have been unable to reproduce the issue. The original project also packages just fine now. I have no idea what might have caused the error previously, but it got fixed with the reinstall of the engine.
