GTA V launcher infinitely loading

Latest GTA V Steam version running on Windows 10 build 14393, ‘vanilla’ GTA V and FiveReborn folders (the latter is located in my desktop)
Screenshot :
CitizenFX.log :

When the launcher says “Rockstar update service is unavailable (Code 213)”, are you clicking the “retry” button instead of “offline mode”?

It loads infinitely, I don’t get any error whatsoever.
Also, FiveReborn was working fine for me like a month ago or so, and I’ve had the same result when I tried an old build of the client that was working for me before, so the issue seems to be on my end.
