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.
