Been there and done that several times. I have had tech support, i have the latest version of the QB Tool Hub, my computer is windows 10 up to date. I've downloaded all the updates available for QB. I have disabled the start up to home page. It's an on going problem and when i run all the components of the tool hub, it seems to run smoothly for a few days and then the same problems pop up. It's very frustrating.
