Vray 5 crashing SUPro 2019 iMac

Anyone else having problems with V-Ray 5 with SketchUp 2019? Mine crashes every time I hit any render type. I can open the materials editor, but that’s as far as I can get. I have reloaded multiple times, restarted computer, etc. Same results.

iMac Intel Core i7, 32GB Ram, AMD Radeon R9 2GB Mojave 10.14.6

Thanks for any ideas!

Same problem with SketchUpPro2020 and V-ray5. Cloudrender crashes constantly. Very stressfull when you have to meet a deadline… Back to Vray4?
