Can't link Epic account to GitHub

I’m trying to link my Epic account to GitHub. But I’m getting the error message “Sorry, but this github account has already been associated with another Epic Games account” and then a long ID. I opened a ticket with the Epic support and they directed me here. I only have this Epic account and only this GitHub account. Any idea what to do (apart from making new accounts)?

Hello, i’m sorry to hear that i’m not the only one having the issue, i’ve even deleted my old github and created a new one with another email. Same issue. Unreal is really having an issue with the authentication or i’m doing something wrong every time
