My Linkedin Account Stolen - I Want Recovery

My LinkedIn account was stolen and I completely lost access even though I first noticed the issue only today. When I checked my email, I saw a message from LinkedIn stating that my account had been opened on another device in a location that is not near or known to me. After this unauthorized access, the attackers changed the email address associated with my account, so I can no longer receive any verification codes or recovery links and I am fully locked out. According to the email notifications, the unauthorized access appears to have started around 31 January. I only realized the problem today, when I received the warning about a new device and then understood that my email had already been changed without my consent. I did not share my password or give permission to anyone to access my profile. I contacted LinkedIn support by filling out one of their official forms and also wrote to them on X (Twitter), but so far I have not received any effective help and my account is still in the hands of someone else. This situation is very upsetting for me because I have just graduated and I have been actively using this account for about four years, carefully uploading every change and development in my education and career during this time. I request that my stolen LinkedIn account be urgently recovered, the unauthorized email change be reverted, and full access be restored to me as the rightful owner. I also ask for an investigation into this unauthorized access and for information on how my account security was compromised, as this profile is very important for my future job applications and professional network.
