You don't specify interface or any specifics of the system, but that's a CoreAudio CPU timeout so I'm assuming you're running a native rig. Obvious questions are about buffer settings, actual routing between Pro Tools and Zoom, are they sharing an interface, if so how? etc. I can say fwiw, that I run Zoom sessions alongside Pro Tools on the same system sharing screens and with Audiomovers all day long without issue, so it's certainly possible, though my rig is HDX.
