This is what I get in the console:

Hi Guido!

As a workaround for now, we recommend specifying a renderer from the command line, e.g. "usdview --renderer Embree".
22.03 does not yet have our full implementation of Hydra Storm for Metal (that's still to come), but it looks like some of the supporting code change are active and that's the source of this problem. Continuing to investigate...

Thank you for the suggestion David, the workaround works fine.
