New error in Cubase 10

Cubase 10.0 has worked flawlessly for the last 2 years, but suddenly started throwing an error when I try to select any of my VST instruments. Error message posted below. I reinstalled Cubase, but no improvement. Wondering if I have too many VST instruments? (About 30, so I doubt this is the issue). Win 10 / 64, 40GB RAM. Thanks.

Could you try in the Cubase Safe Start Mode [Disable preferences], please?
