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.”

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