Constantly freezing because of resource packs in my Minecraft files that I can’t delete

 
 
So I got a problem with Minecraft freezing constantly because of some in removable downloaded resource packs, and add ons. I get about 30 minutes before I have to reset my game because it began freezing and get about another 30 minutes without it freezing again. I figured out that these add ons I added before the caves and cliffs update were causing it. I tried looking up how to remove this but nothing worked. I went back to the app on my Xbox called MC add ons manager but the app had a update and made it to were I can't remove the add ons from there. So the add ons and resource packs are just sitting there in my Minecraft files so this is causing me to freeze over and over. I tried going to storage in the Minecraft setting and removing them from there but the game never gave me a option to delete it. I really need help I can't even play the game.
