I can’t see your video but I see strange behaviour when viewing your SketchUp file. The model was there, then disappeared without me zooming at all, just panning a small amount and it vanished.

You have some very large geometry which is causing the camera to behave strangely. For example this component:

3DGeom~2258_Defintion#2

Has geometry that extends from -26km to 26km below and above the xy (red-green) plane.

Another example, 3DGeom~2292_Defintion#2:
