Please, help me, I’m on the final stretch, this is my first game that I’ve made in 2 months (and in general, learning ue5), and when I start building the project, I get the same error: PackagingResults: Error: Unknown Error. I’m a beginner, I’m a clumsy person, but I’m already tired. Please help me.
Hello again @AngFallen ,
That’s awesome that you’ve made it to the final stretch , finishing your first game is a huge milestone, especially after just two months of learning UE5. Don’t worry about the error, it happens to everyone at some point. Could you share the full build log ? Once we see that, we can figure out what’s really causing it and get you across the finish line.
Before I send it, I’ll ask if the project might not work if the names contain German, Russian, or other words.
From what I’ve researched,If you mean that your project or its folders contain characters outside the standard range (like accents, umlauts, or letters from alphabets such as Russian or German), it’s very likely that Unreal will fail to build or package. It’s best to make sure the entire path, from the user name to the project folder, uses only letters A-Z and numbers. There’s actually an older post that mentions this issue too.

These are the last things he wrote to me.
The problem, as we mentioned before, seems to be characters that aren’t allowed. You can try building it in a simple path like D:\UE5\NewProject. A clean, short path should fix it.
It means the compiler couldn’t find or access the file because the operating system doesn’t recognize that corrupted path either.
So I just need to change the name to English?Should I change the folder name too?
From what I understand, yes, that should make it work
The error didn’t go away, so I created an empty LV and got the same error there.
Try deleting the Intermediate, Saved, and Binaries folders before packaging.
You can also run Verify on Unreal Engine from the Epic Games Launcher to make sure no files are missing or corrupted.

If none of that works, I honestly can’t think of what else it could be
I also have some models in Russian, do I need to correct them too?
I created a new project and tried to make a build, but I also got an error with the 5.4 engine version.
