Cant make new C++ projects

I get this error every time I try to make a new C++ project

An error occurred while trying to generate project files.
Running C:/Program Files/Epic Games/UE_4.18/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“C:/Users/john/Desktop/test/test4/test4.uproject” -game -rocket -progress
ERROR: ‘.’, hexadecimal value 0x00, is an invalid character. Line 1, position 1.

Heres a link to a video of what im doing: Video of me trying to make a project

The uproject file seems to be corrupted. It’s a text file but there is a null value in it.

Wait. This is confusing. Are you using the source-built engine (from github) or the one you install from the launcher?

The first error that says build manually – that means it wants you to build the project from Visual Studio. The null in the generated uproject is baffling.

its from the launcher and i went into VS and built it and got a error from there as well
