Hi,
  If you set a Windows global environment variable VMDNOOSPRAY to 1,
that will prevent VMD from trying to intialize the Intel OSPRay ray tracing
library, and avoid the problem you're seeing.

Using the Windows program/search box, you can type "environment" and
select the "Edit the system environment variables" control panel,
and after opening that, you can click on the "Environment Variables"
button in the System Properties window in the Advanced tab.
After clicking on the "Environment Variables" button, you should
have a window with both user, and system-wide environment
variables shown, and you can add a new one "VMDNOOSPRAY" with a value of 1.

Best,
  John Stone
