Missing or deleted assets

I'm currently following tutorials to gain some knowledge in Adobe animate. I got stuck however when searching for the "Bunny hop" in the animated assets panel. One of them was missing so i only had the bunny that hops in one spot as apposed to moving across the screen. I dont recall deleting this at any point. Though just in case, i installed other recent versions of Animate and found those to be missing the asset also. Is this a problem anyone has encountered and also is there a way to retrieve deleted assets if i do ever need to? Thank you
