Token Validation Failed

Hello, my account has been hacked by the bookmark scam and im still logged in and since Roblox support isn’t’ replying, is there any way to leave my group or change ownership because it just gives me an error when I do it on Roblox and when I use the api it gives the error Token Validation Failed

Full Error:

	
Error: response status is 403

Response body
Download
{
  "errors": [
    {
      "code": 0,
      "message": "Challenge is required to authorize the request"
    }
  ]
}

It also wont let me access my settings and it just gives me an error no matter what I do, everything in the account settings has been changed too even email and pin.
