Packagin failed! 5.4.3

[Ninja699669]

"This is so hard to identify why it happens like that?

Today, the project crashed and won’t launch anymore. Clicking to open the project and it crashes directly.

I searched by deleting folders until I found that without a folder, the project opens. Then I did the same inside that folder with all subfolders and files until I found the file that was causing the project not to open. And guess what? This file I never edited before or touched, so it’s crazy - why did it happen like this?

That was the problem solved.

Now, the editor opens nice; I can play in the editor, no bugs, no errors; I can edit files, save them, etc.

But when it comes to packaging the project, it doesn’t take 4 seconds and packaging fails!

I tried all three packaging configurations by default (shipping-development-debug game) and it’s just the same. As you can see in the video, there isn’t much information, so how can I pretend to solve this?

Creating a new project works fine; everything works fine. It’s just this project, so it’s not Visual Studio or any dependencies.

What could be?"

"Why does this happen? I didn’t even touch that file in my life, yet it caused this kind of problem.

And don’t tell me it’s a mystery, because as you know better in programming or painting with blueprints, there are no mysteries. What you write is what you get, and that’s it.

If I didn’t touch that file, why did I get this?"

And the UBA txt file is telling to check doesn’t exist

I forgot to mentions some hints

Already tried on another PC
Reinstalled windows on other pc and installed visual studio
Reinstalled and installed on both computers Unreal engine
Tried deleting all the folder and also some of them and also 90% of them
These folders are all and only left with the uproject name , the folder config and the project content
the second try leaved the same folder but also the saved and so on with mixing folders etc
The actual change that that i made just like 20 min before this happen was setting the hole project folder to share on OneDrive
and by spelling before i mean just before started the first error that project was unable to open

How may I resolve an error "Couldn't find target rules file for target 'ProjectName' when building a project?

Hello, I have just started a new project using Unreal Engine 4.18 with nearly nothing in the project and had added a few C++ files to the project. These C++ files worked well in the previous versions of Unreal Engine. Every time I try to compile them I get the following log message and have no idea how to solve this one. I have found a few other posts on the same subject, but nothing relating to the issue dealing with Unreal it self. Please, will some one help me out with this. Here is a copy of…

Thanks for your quick answer, the files Target.cs are there in the source folder
The entreprise option in the uproject i dont have it its all clear

[KryogenicGames]

[Ninja699669]

yes i can compile whatever project i want but not the current one

[KryogenicGames]

could you try to back up Build folder from your project and copy one from 3rd person template and try to package

[Ninja699669]
