Unable to launch Create BETA 2022.1.2

Installed Create BETA 2022.1.2, was working two days ago. Today, clicked on “Launch” and nothing happens. Installed and downgraded to 2022.1.1. No help.
I am running Windows 11 with RTX 3090. What do I need to check? Many thanks

Just upgraded to 2022.1.3, still unable to launch Omniverse Create
