Check if you have “Use UI Store” set to true.

This will package your project as a .pak, .ucas, and utoc file.

For some reason, when trying to create a patch, these files will cause this error.

Set “Use UI Store” to false and package again to only get a .pak file.

Now your patch build will have only a single _p.pak file that should work correctly as a patch for your base build.

Just an FYI…

I incorrectly typed “Use UI Store”. It should be “Use Io Store”.

Also, you find it in Project → Packaging in the Project Settings.
