Could not validate game ownership - unable to authenticate with Rockstar Games Services

[Arkadiusz_PELAGIUSZ]

What is the issue you’re having?

When I launch FiveM, it opens Rockstar Games Launcher and asks me to log in. After logging in, FiveM shows the error: “Could not validate game ownership! If you are running this as administrator, please launch it as regular user.”

Error from log file: “Could not validate game ownership! If you are running this as administrator, please launch it as regular user.”

System: Windows 11, GTA V on Rockstar Games Launcher, Administrator account.

Additional comments

Rockstar Games Launcher works fine on its own. Issue only occurs when FiveM tries to authenticate. My Windows account is an Administrator account.
