When I created the Lyra project , I gave it a different name. Normally this would change the name of the exe file it makes when compiled. But for some reason it didn’t and I changed the name in the Project Settings to the same name I gave the project. The Uproject Name is Not Lyra and it is correct in the Default Engine.ini as well. But still the final EXE file is called LyraGame.exe. I have never encountered this before now.
