This is on a new, clean install of GTA. When trying to open FiveReborn, Social Club opens then starts to load, then quickly gives me this error and FiveReborn stops working. After I close the program, it gives me this error for CitizenFX. Sometimes the social club error doesn't load before FiveReborn crashes.
CitizenFX.Log is http://pastebin.com/U8n8rGE8.
FiveReborn, GTA, and Social Club's subprocess.exe are all added to the antivirus (Panda and Malwarebytes) and firewall exclusions. Same thing happens even if I disable firewall and AV's.
I'm on Win 7 64 bit, GTA is updated. Running it as administrator and/or in compatibility mode for Win 7 gets the same error.
Regular game starts up fine.
