I started a new blank project on UE 5.5.3
I added a simple UObject class ( that is empty ).
I quit the project, run the .sln to build the solution.
The command ““D:\Unreal Engine\UE_5.5\Engine\Build\BatchFiles\Build.bat” SubvacistaEditor Win64 Development -Project=“D:\UE-Projects\Subvacista\Subvacista.uproject” -WaitMutex -FromMsBuild -architecture=x64” exited with code 6.
How is that possible ? No error in my class nothing, just the Engine that doesn’t want to collaborate.
