Settings Pages + Conditional Logic breaks Oxygen editor widget functionality

Metabox conditional logic and settings pages seems to be causing an issue with Oxygen admin ajax. The line referenced in one of the errors points to a Gutenberg integration function in conditional logic extension. Whatever it is, it's causing Oxygen to fail every time I enable metabox conditional logic extension and have a settings page built with metabox settings page extension.

Steps to reproduce:
1. Install MB core
2. Install AIO, enable Settings Pages/Conditional Logic
3. Add the settings page sample code from https://docs.metabox.io/extensions/mb-settings-page/
4. In the Oxygen editor add a > Basics > 'Section'
5. Inside the section add a > WordPress > Widgets > 'Navigation Menu'

Expected behavior:
The widget settings should load in the Oxygen side panel and the widget should be displayed in the editor window.

Actual behavior:
Widget settings display a spinning wheel or an error message, widget doesn't load in Oxygen editor window.

Error messages:

• Chrome dev tools -
  Failed to load resource: the server responded with a status of 500 (Internal Server Error)
