Regret using shorts to grow my channel

I have a channel with 21k sub. I grow this channel with only shorts now I regret because all the shorts subs don't watch my long vids my niche is gaming and only my shorts video getting views 15k everyday. I want a suggestion from all of you that should I make a new channel only for long videos or should I upload videos in my main channel because my all long vids getting 4-5 views and I don't know what to do and I don't use shorts related views because I know my viewers don't watch my long vids.

Sorry for my english and not good at it still learning I hope you guys understand my feelings
