VCV Rack 2, Ableton, and Core Audio

I have the same problem: As soon as I change the audio driver to CoreAudio and choose ES-9 as a device Ableton audio output stops and the window type of freezes. Critical seems to be the device, not the driver (at least is that the point ableton freezes). Interestingly, the test tone (from within Ableton preferences) still works. My workaround is (as already written): reloading the audio driver in Ableton preferences restores control of Ableton and thus avoids the need to restart Ableton.

Done that, everything is super stable so far. The workaround saves a lot of time. With Rack 2.03b Ableton crash right from the start. I already wrote the bug to the support.
