I updated my Epic Games Launcher and more than half my library is missing

Summary

Had an old email which I used to purchase many unreal engine projects. Recently I updated my email address on file to a new email.
Everything was fine until I decided to download a project. The downloads were stuck on initializing, so I re downloaded epic launcher which ended up removing my whole library and I only see stuff i got with my new email address.
How to access my old library?

What type of bug are you experiencing?
