Uncaught TypeError: Cannot destructure property 'A' of '_ember.default' as it is undefined.

Describe the bug Exception in console: Uncaught TypeError: Cannot destructure property 'A' of '_ember.default' as it is undefined.

From time to time Ember also said that this is not an Ember application. I suppose because of this is error.

With more loaded application (tailwind, ember-cli-mirage, some components, some routes, some models and so on) it starts failing more often. When I did mirage mockups, and gives this error in 50-60% of refreshes.

To Reproduce

1. Install ember-cli 3.26.1, and ember-inspector 4.4.0 in Google Chrome browser
2. Create new project and start it: mkdir tmp-dir; cd tmp-dir; ember init; npm start
3. Open http://127.0.0.1:4200/ and manually add some non-existent url like http://127.0.0.1:4200/some/url
4. Open chrome inspector dev tools (F12)
5. Open console
6. Now spam Ctrl-R to refresh page. After time to time there will be exception:

VM4178:61 Uncaught TypeError: Cannot destructure property 'A' of '_ember.default' as it is undefined.

    at requireModule (<anonymous>:42:28)

Research showed that it points to this line: https://github.com/emberjs/ember-inspector/blob/master/ember_debug/adapters/basic.js#L3 Ember object here could be undefined.

Expected behavior No exception

Environment ember 3.26.1 node-inspector 4.4.0 google chrome 90.0.4430.212

We just tagged v4.4.1 with a fix (though there may need to be more fixes to follow).
