Hello, I spend hours debugging this issue.  
When I start GUI, there is a common error:  
` Cannot read properties of null (reading '_getComponent')`

First I removed node\_modules and installed them again packages:

```auto
"@babylonjs/gui": "^7.1.0",
"@babylonjs/loaders": "^7.1.0",
"babylonjs": "^7.1.0",
"babylonjs-loaders": "^7.1.0",
"babylonjs-serializers": "^7.1.0",

```

I run the initialization of GUI after the scene is created (tested even with timeout).  
the `EngineStore.LastCreatedScene` is null;  
This issue does not appear when running with CDN; I tested on Playground and jsFiddle.

But when I run it with import packages:  
`import * as GUI from '@babylonjs/gui/2D';`  
it didn’t work.

I have created a very simple repo extracted from my game workflow to show the issue.

Just run `npm i` and `npm start` - and open dev tools to see the error message.

I think you’re mixing UMD and ES6 packages?

the packages starting with @ are ES6, the others are UMD.

Yes, indeed, I didn’t notice that there are two versions.  
Now I also see I used loaders from both.

Thank You!
