'Engine Versions' and 'My Projects' not showing in Epic Games Launcher

Problem: I upgraded my PC and got new hard drives but after updating the Launcher it is no longer picking up my ‘Engine Versions’ and ‘My Projects’.

I have a folder named ‘Unreal Engine’ on my D drive with ‘Builds’ ‘Epic Games’ and ‘Projects’.

Inside the ‘Epic Games’ folder are my individual UE4 engine version with a seperate ‘Launcher’ folder.

Inside the ‘Launcher’ folder is ‘CrashTokens’ ‘Engine’ ‘Portal’ ‘VaultCache’.

In short:

Launcher exe located: D:\Unreal Engine\Epic Games\Launcher\Portal\Binaries\Win64

Individual UE4 versions located: D:\Unreal Engine\Epic Games

Individual Projects located: D:\Unreal Engine\Projects

Why is the launcher not picking up my projects and engine versions that i already have on disk?

I tried opening a project with the Epic Games Launcher and nothing happens except for the Launcher opening.

Would be awesome if you could tell me how to get the Epic Games Launcher to recognize my previously installed versions of Unreal Engine.
