Inspector crashes with Embroider built application

[andsmedeiros]

Describe the bug
Stock install from ember new test-app --embroider makes the inspector crash internally

To Reproduce

• Create a new application and serve it
• Open the inspector; it says the application was not found. The console logs exceptions not caught (Uncaught TypeError: run is undefined).

Expected behavior
The inspector should correctly load

Environment
ember -v:

ember-cli: 3.28.1
node: 14.17.3
os: linux x64

uname -a:

Linux excelsior 5.11.0-37-generic #41-Ubuntu SMP Mon Sep 20 16:39:20 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Firefox 93.0

Additional context
With broccoli the inspector works ok, but logs lots of deprecations.
Logs of a fresh install for both build systems are included:

ember-inspector-broccoli.txt
ember-inspector-embroider.txt

Just ran across this, a rough workaround I've found for Chrome has been

• close dev tools
• reload page
• open dev tools
• switch to Ember dev tools and they should be working

@ef4 @chancancode do we need to do anything special to support embroider?
