Do you happen to have an AMD graphics card in your machine? There's currently a known issue in combination with new AMD drivers and Rhino that may cause a crash like that. We've fixed that for the upcoming 2.7 release already. And in the meantime it should work by rolling back your AMD drivers back to version 19.12.1.
Hope that helps!
I have NVIDIA graphic card, and I have sent you the logfiles as requested! Thanks a lot!
