Engine build from source code with error for cvtres.exe

Hello there @Jacob_Vo!

Checking through your log, this definitely looks like an issue with your Visual Studio setup. There’s an error stating that “The target framework ‘net6.0’ is out of support”. Per UE’s requirements, you should be working with .NET 8.0.

So, the first step here would be to review your entire setup, and make sure that all components and addons are installed, and using the correct versions. You can check a full guide about it here:

And I would strongly advise against having two versions of anything active at the same time, stick to the versions on the guide only. Now, once you have reviewed the VS install, if the issue persists, there’s another angle for the issue.

You have multiple errors with cvtres.exe failing to interact with other files, meaning something could be interfiering with the operation. I would make sure that your UE project is not located in any folder with limited or restricted rights (anything tied to OneDrive or cloud storage), and check if any active security is picking up cvtres.exe as a threat.
