My LinkedIn Account Has Been Hacked and I Can't Recover It

I am facing a serious issue with my LinkedIn account. My account was taken over by unauthorized individuals, and despite my efforts, I haven't been able to regain control. The email address associated with my LinkedIn account, '[email protected],' received notifications of changes made to my account, including a new name, 'a** a***,' and a changed password, which prevents me from accessing my own account. I can confirm that my email address remains the same. You can easily verify my ownership through the screen captures of my past posts on my LinkedIn profile: https://tr.linkedin.com/. The urgency of this matter cannot be overstated. I kindly request immediate assistance in resolving this issue. Upon entering my password, I am prompted with the message: 'Enter the code displayed in the Authenticator app.' Your prompt action is greatly appreciated.
