I don't use it, but I often see posted reports here of it doing strange things like that. I think your issue might be more quickly resolved by posting here: [URL]  
Running Windows 11 Pro 22H2 Insider Beta Channel. Dell XPS 8940. Out of the blue the SupportAssist app (v3.11.1) has stopped working. When I run the app the circle twiddles around for ages and eventually ends up with the message "This is taking longer than expected. We recommend restarting your PC and trying again." Restarting and trying again makes no difference, still hangs and then fails. I downloaded the latest version and tried to install, same thing, same message.
