'Can you turn a Unreal Project .EXE into .uproject?

I have a .exe file, called Sonic Infinity Engine Plus, that was built in UE4. This was released public without source code download, so I am unable to modify it.
However, this game was released with an Unreal terminal (accessed by the `/~ key). I'm wondering if there is any way I could retrieve the source code.

If anybody knows such command, like build source, it would be helpful to know.
If you need more information I couldn't think of off the top of my head, please let me know!


Thanks, Omega207

As user Rotem replied, there is no known way to retrieve the "source code" as I thought it could. This is due to complications with decompiling UE4 source code. This is due to the fact that Unreal tends to hide source to most who use it, and is therefor up to the creators to distribute source code (which is all the files creating the .exe file).
Since the source was never distributed public, there is officially no possible way to modify this engine as the creators meant it to be.
