Unfortunately, that didn't help. The driver I was using was about 2 years old and is whatever MS or HP (it is a 7 year old HP laptop) were offering. I did find a driver about a month old on the NVIDIA site, but, the behaviour is unchanged. And I still have "Surface Version: 4.4".

To add another weirdness, the above attempts were from the Windows command-line. If I start it from PowerShell, it runs. The same shader compile message is shown, but, the editor stays open and can be used with no obvious problems. And if I start the GUI in debug mode from PowerShell, the editor and viewer both open correctly.
