Thanks for reaching out. Do you have any strikes on your channel? Channels that have demonstrated more “unhealthy behavior” will not receive access to Stories during the initial expansion, for example, channels with 2+ strikes. Let us know!
Looks like you've deleted your channel from your end. If it was done through YouTube settings, you won't be able to recover it. If it was your Google account you may be able to recover it: https://yt.be/help/AwNG . Hope this helps.
