Rhino crashing with material commands

Hello
I’ve tried 3 separate times to assign a double sided material with standard Rhino Metal and Paint materials, and crashed every time. After making the double sided material, I right click to apply material and it would crash. However, when I dragged the material directly onto object, it worked fine.

Also crashing when I click the + icon to create a material.

here’s the crash report. First one is for the double sided material, the second is the general material creation. Tried to include the whole crash report in 2 separate posts but each crash report exceeded max character limit so just posting abridged version.
Thanks!

This crashing in the latest Catalina update is a known bug.
We have reported it to Apple and we understand they are working on it.

I think if you upgrade to Big Sur, you can get past the problem.

Thanks @John_Brock
I am running Rhino on Big Sur, hopefully there’s a fix soon in the upcoming SR’s.
