Live Coding failed Error when creating a C++ File

Whenever I create a C++ file it exists, but Unreal Engine does not recognize it. After creating it, it puts the error “Build failed” and a little “Live Coding Failed” box at the bottom right.

Greetings @Master101.5

Are you building from within UE? You’ll need to do that rather than from the IDE. UE5+ has live coding enabled. If you want to double check the settings try Edit>Editor Preferences>General> Source Code(As well as the ‘Live Coding’ section) and ensure they’re enabled. I hope this helps!

I did use Unreal Engine to create the C++ file.

I found the problem, I installed the DLSS plug-in incorrectly
