Cannot read properties of undefined (reading '_application'), Maximum call stack size exceeded

I’m seeing this in all projects I’m working on!

To Reproduce

1. Open an Ember app in the browser.
2. Open Ember Inspector.
3. Refresh the browser tab.

Expected behavior

The app is working, Ember Inspector is working.

Actual behavior

The app crashes, Ember Inspector won’t even start.

Uncaught TypeError: Cannot read properties of undefined (reading '_application')
