This message is for the dev of cfx.
I got fixed this issue right now, a few minutes before formatting my PC to try fixing this problem.
I think you should really add this to any FAQ or other places cause i’m sure this can fix other players problems.
I deleted 2 folders -
%localappdata%\Rockstar Games
%appdata%\CitizenFX
Seems like deleting GTA and FiveM ain’t deleting those folders and something got corrupted there.
