I can't get Lightroom to launch. I have tried uninstalling and then reinstalling everything, including the cloud and I'm still only able to get the splash screen with a rainbow wheel. The app says it isn't responding and I have to force quit. I have the most recent version of Lightroom classic installed from the cloud and I use a MacBook Pro with OS 10.13.6. It was working for me and then stopped launching about a month ago and every time I chat with support they take over an hour and fix nothing. So frustrated!
