Unable to Break Raid

I am unable to break my Raid 5 array, I’m getting an error saying the raid is being used by kernel. I tried to use the steps outlined in this post but I was unable to stop the Files app, and when I attempted to stop md0 raid, I was told I need to be a super user.

Apologies if I’m missing something very obvious, still pretty new at linux and servers. Thank you for any help!
