Unity Editor Crash Using OVRLipSync On MacOS

I'm hitting a strange issue that I can't explain.

We're developing a VR app in Unity and I've recently added the OVRLipSync for mouth movements but I keep getting Unity Editor crashes every time I run our application, even in the sample scene included in the package - It's 100% reproduceable.

I have noticed however if we create a whole new Unity project (same Unity Editor version) and import the OVRLipSync package then run the sample scene it works fine (obvious after allowing permissions to the bundle file via System Preferences). However the crashes are consistent in our own project we're trying to add OVRLipSync to, so something is definitely amiss in my project specifically.

It's also worth noting that it is only crashing on OSX, not Windows - I only have one OSX device so it could be specific to my Macbook but I'm unable to confirm that.

At first I thought maybe it was OSX not having permission to the OVRLipSync.bundle file but I've ruled this out as I've re-imported the bundle file and allowed permission via the System Preferences -> Allow Anyway option.

If anyone is able to help it'd be a huge relief as this is causing us a lot of issues at the moment as we're having to add defines in our code to ensure nothing involving the lipsync is used when we're developing in OSX.

Here's my Editor.log file:
