Fix This, YouTube!

I had a YouTube channel with the handle @banana-2007-n5n and I was about to upload a new video when I suddenly noticed that my channel was no longer available. When I open YouTube, I only see the generic “Sign in” page with a blank profile icon, as if no account exists. When I sign in with the email I always used for this channel and check YouTube Studio and the “Switch account” section, my channel does not appear anywhere. I have not received any email or notification from YouTube explaining a suspension, termination, or any other action regarding my channel. I request that my YouTube channel @banana-2007-n5n be checked in detail, that I be clearly informed about what happened, and that my channel be restored as soon as possible if it has been removed or hidden by mistake.
