Here is the note I posted for help in the YT Creator Forum..... since I can't find a way to contact YouTube and my earlier support email no longer gets delivered.
Why are my videos disappearing off my YouTube channel?
I have published 1,181 as shown in my channel "about" info.
My content showed 769 earlier today then 716 an hour ago and right now it says there are just 709.This is terrible. It appears I have lost about 472 of my videos and more are disappearing every hour. They are all my copyright and my content.

I will update here if I learn anything.
