The display of the 3D model in the editor disappears.
In the PlayCanvas editor, such a problem sometimes occurs.
The model’s visualization disappears from the 3D editing window, and in no way can it be returned back.
Moreover, if you select a camera, everything is displayed in its display.
So far I have found only one solution - to create a project archive, and then upload it.
But it is inconvenient.
Tell me, what could be the matter?
