,,You haven't signed in this way before"

Hey guys, you’re pretty much my last hope here. I’ve been trying to log into my Epic Games account for about 3 months now, but I keep getting the same error: “You haven’t signed in this way.”

No matter what I try, it just won’t work. I used to always log in through my PSN account, but now it simply won’t let me. I even reached out to support, but it honestly felt like talking to a wall. I sent them screenshots proving that I had this account, and I even still have games installed on my PC that I got from Epic. It’s like like my old account didn’t even existed.

Has anyone else run into this issue? And if so, how did you fix it? Any help would be greatly appreciated!
