Is there any hope?

I have a made for kids SHORTS channel with 395k subs. In October I got 80 m views. On the day I reached 200m views in total, in a matter of an hour, my views dropped from 3m a day to 30k a day. This happened 7 days ago and still hasn’t gotten any better. All my new uploads only get views from my subs (99.9% subs). Do I wait for a miracle or give up and start a new channel?
