Error 404 when trying to access respository

I am trying to access this repository as I am in dire need of its source code, however, despite being linked to Epic, my account is behaving as if it is not. I have received confirmation mail that I am linked, I received the invitation, my account shows as linked from the Epic side, but there is no organization in my profile in github. Please assist. The repository in question is this: https://github.com/ruyo/UnrealEngine_VRM4UPlugin
