Invoking `scene.debugLayer.show();` no longer works. No changes to the imports and it suddenly stopped working. Error: ```auto babylon.js:16 Uncaught (in promise) TypeError: Cannot read property 'getClassName' of null at babylon.inspector.bundle.js:35 at Array.filter () at t.renderContent (babylon.inspector.bundle.js:35) at t.render (babylon.inspector.bundle.js:35) at fl (babylon.inspector.bundle.js:51) at gl (babylon.inspector.bundle.js:51) at Ki (babylon.inspector.bundle.js:51) at Ui (babylon.inspector.bundle.js:51) at Fi (babylon.inspector.bundle.js:51) at _i (babylon.inspector.bundle.js:51) ``` The imports: ```auto Babylon.js sample code ``` ---

Ohhhhhh it sounds like a bad bug related to the content of your scene ☹ Is it possible to access your scene or to repro in the playground ? I really want to tackle this on as a priority. ---

Also do you know when did it stop, it might help me checking into the changes. ---

I would say it stopped withing the last 20 minutes from when I posted. I don’t have a playground for it, it’s a local project. ---

So this would be our latest update let me check what changed in there which might be related. ---

There is nothing related to inspector in the latest change ☹ Do you have the project online I could access ? ---

I unfortunately do not have it online. I will ping you when I put it online - but given your reassurance, I will dig in my code if anything is off. Thank you ---

Actually, it looks working in the playground and sandbox but a bug in the inspector linked to your scene data (bug would only show in case of a special condition in the scene) is highly possible.
