Ace Pro 2 Condensation Issue: Is Ace Pro 2 weather-proof without lens guard?

To make my life easier, I was wondering if anyone here from Insta 360 could tell me if the Ace Pro 2 is still weather/water proof when the lens guard is removed?

In cold conditions the inside of the lens guard mists up when my camera gets warm. A real pain, but manageable if the camera is still weather-proof.

Thanks.
