Cinema 4D R21.1 freeze & crash mac os 10.15.2 while compiling scenes on 5700 XT. There are nothing helps until hard reset / restart.
For example you can test this scene: Low poly Living Room 3D Model - Free C4D Models
I try with compiling shaders and there are nothing.
The same system (intel i7, 5700 XT) with the same software (C4d r21.1) work stable under Windows 10.
