Hi, I’m having the same problem as you. I contacted support and they responded quickly, sending me this (I’ve already followed the steps and it’s still not working, and 24 hours haven’t even passed yet):
Hello,
Thanks for reaching out. We’re sorry to hear you’re running into this issue.
The error you’re encountering usually means that your Rockstar Games account is currently linked to another FiveM session. In most cases, this happens when the account has been accessed or compromised by a third party.
To secure your account and prevent further access, please complete all of the following steps:
- Change the password for your Rockstar Games account/Epic Account
- Enable Two-Factor Authentication (2FA) on your account
- Change the password for the email address linked to your Rockstar Games/Epic Account
Once these steps are completed, access from any unauthorized FiveM sessions should be blocked. Please note that it can take up to 24 hours after securing your accounts for this error to fully clear.
