Can't Delete Video

I've got a rogue Vimeo video that won't stop auto playing on page load and despite deactivating both our video-related plugins, I cant remove it from the page to see if reinstalling it would fix the issue. The video was placed in a Video Sidebar widget in a custom field. When we decided to stop the autoplay behavior, I set the auto play dropdown field in the widget to "No." It kept on autoplaying anyway.

Went to Vimeo and made sure no settings were set to auto play or loop. So no help there.
Would sure appreciate it if one of your crew could take a look and see if you can get it not to autoplay or tell me why I can't delete the darn thing.
