Rhino 8.23 freezes my system: it hangs for a while, Explorer usually crashes (its windows have to be reopened), but in a minute or so the system responds again, only to freeze maybe few minutes later. After closing the Rhino instance, Rhino keeps running in the background, hogging the CPU!
I noticed it happens after I’ve started adjusting material of a layer.
With other file it helped that I put only the strictly necessary geometry into a new blank document.
Windows 10, I have an old Radon RX Vega, the latest driver
