Looks like you have a hole in your tube and its forcing air and moisture out of the valve hole as the tube loses pressure. Also that retaining nut is supposed to be against the rim, not up by the cap.

If this is a tubeless setup, then the valve lock nut should be screwed tight against the rim, pulling the valve into the valve hole to form an airtight seal.
Most tubeless valves include a rubber o-ring that sits between the rim.ans the valve to help prevent the valve lock nut from marring the rim when it’s tightened down.
If this is an inner tube, then no issues. There was likely water in the rim void that’s being forced out by the pressure of the inflated tube.
