I think I might have deleted some files that are required to run all the windows apps like Store, Groove etc. I can't open the apps but when I try they just flash on the screen and shut down. I tried this dudes https://www.youtube.com/watch?v=qh-yYa4CKg0 first method using Poweshell but it said that the files don't exist.

I just want Groove back desu. Can't I just download all the app files somewhere and skip the files I already have like copy pasting images from one file to another?
