Thank you very much, everything worked. If someone gets error "invalid escape sequence '\s'" when generating stubs it because you are using a python version higher than 3.9. At 3.9 everything is ok.

Confirmed it's a bug on OSX version - running on macbookpro M1 max.

I wouldn't say this is a bug, SideFX described it in the documentation. New COP requires vulkan viewport, but it is not implemented on macos. I also faced this problem

- Native display of COP nodes in the Scene Viewer.
- The Vulkan viewport isn’t supported on macOS. MacOS uses the OpenGL viewport renderer.
