Scene in IFRAME works only in Chrome incognito mode

When viewing a scene in an iframe, the browser crashes, but if viewed in incognito mode, everything works.
Tell me what could be wrong?

As always, there's no way to help unless you provide a repro link and repro steps.

On Chrome desktop via WebXR emulator it works correctly.

I still need repro steps. Are you saying 3D mode is crashing or AR, or both? Also, I notice on your link there are several red errors in your console. Have you looked into those?
