YouTube Deleted My Account with 7 Years of Playlists and Subscriptions without Reason

I shared a video on my YouTube account, set to private so only my friends could view it. Before they even had the chance to watch, both videos were removed, and my account was deleted without any clear explanation. The videos didn’t contain anything inappropriate—they were simply reposts of previously shared content meant for a small group. I’ve been using this account for 7-8 years, and it contained all of my carefully curated playlists and subscriptions, which are very important to me. Losing access to them has been a huge inconvenience. I am asking for my account to be restored so I don’t lose all the content I’ve built up over the years. I hope YouTube can address this issue quickly.
