Trying to use virtual background without a green screen - "computer doesn't meet requirements"

In Meetings, in Virtual Background, when I try to Choose a Virtual Background, the background I select is muddled - partially on, partially off. When I try to uncheck the "I Have a Green Screen" box, I get a dialog box - "Computer doesn't meet requirements. Your computer doesn't meet the minimum requirements to use this feature without a green screen background." None of my coworkers have this issue, they have the same permissions as me and are able to use virtual backgrounds fine, and they don't have green screens either. Anyone know what the issue might be?
