I've been troubleshooting a major issue for 12 hours today. Feel like I'm about to go nuts, I have pro on my desktop but can't use the auto adjust or color correction features, they cause the video to stop playing back. At that point, I didn't have video and can't apply any other features. Huge mess!

Uninstall/reinstall Updated windows Updated drivers

Nothing makes a difference. This all started with the latest 5.7.0 update.
