[WPMU DEV Dashboard] The WPMU Dev Dashboard plugin cannot be deactivated

I have tried to deactivated this 12 separate times across two days. It simply refuses to deactivate - even though it says it has been deactivated - please refer this screenshot https://www.screencast.com/t/5ooRrDJcOQl
Unfortunately this just just adds to my frustrations with this product.
Thank you.
