Friend request/invite issue

exoticpain

For years I started to randomly have a bug where I couldn't invite or join my own friend but I ignored it since he always joined me. Just unfriended him to test if I could fix it but now I can't even search him up and vice versa. I am xExoticPainx #c10f on Playstation (5) and he is Rias Gremory on Windows PC 1fc2
