Player with same identifier error

[Lv01Metapod]

When one of my friends is in a server, I cannot join without risk of getting banned. Which has happened on HighLife RP, thankfully we were able to get it lifted. Anyways, FiveM thinks we have the same “Rockstar License” - I’m not quite sure what that means - but we do not even own the game on the same platform? His version of GTA is via Steam, and mine is via Social Club. I’m not quite sure what to try or do even to begin. I also do not know where to view a “Rockstar License” on my computer.

GTA V version? 1.0.231.0
Up to date? Yes
Legit or Pirate copy? Legit
Steam/CD/Social Club? Social Club
Windows version? Windows 10
Did you try to delete caches.xml and try again? Yes
