"App totally working properly"

Ever since the most recent Android update, a week or so ago, my phone has INSISTED that my YouTube app isn't responding when I load it. This is relatively normal because I have a lot of videos downloaded, and it used to stop asking If I'd like to close it after a couple of minutes. Now it asks every five seconds even when it is playing videos and letting me browse, and performing to all meanings of the phrase "working as intended". Whenever my phone's screen is turned off so I can listen to my podcasts, music, shows, etc it force closes the entire app and clears the memory so It happens all over again when I load the app. Is there a way to disable my phone from closing my apps without my permission, and to disable or at least limit the frequency of its pop-up message? Of which if I click anywhere else on my phone, it assumes I meant to close the app, which is working properly.
