pro tools 11.3.1 waiting for video operation to complete?

Hi,



What is pro tools 11.3.1 waiting for video operation to complete?



I once imported a music video into my session. I've delete this and now I get in pro tools 11.3.1 waiting for video operation to complete when I close out my session. It's a drag it slows my work flow down.



Please advise anyone?



Thanks
