A poor venting system or clogged venting stack is always the primary reason to empty a toilet bowl all of a sudden.

Possible Cause NO2. – Why Does My Toilet Bowl Empty Itself Due to Hairline Crack in Bowl or Drain outlet
A Crack Bowl itself can cause an empty toilet bowl. Sometimes after a long time of use, the toilet bowl can crack for a variety of reasons, and it is most common in two-piece toilets.
An absolutely fine, hairline crack can be the cause of the drain out of the bowl, but still, the tank is full.
Or, there is a crack within the sewer outlet, which reduces the water dramatically- from the bowl.

Possible Cause NO3. The weather sometimes seems to dry out the bowl
The hot climate eventually dried the bowl. If you live in a hot climate, it shows that water evaporates from the bowl significantly.
This happens in specifically unused or not frequently used toilets.
To fix this Issue
Try to use the toilet more often and see any differences will show or not.
I believe, cover the toilet lid, so water evaporation has become less.
The last possible cause a toilet bowl drains completely is the P-trap.
Possible Cause NO4. Water not Staying in Toilet Bowl but the Tank has No Issue Due to P-trap
P-trap is a U-shaped curve in the pipe installed near the drain to prevent gasses from traveling up the pipes.
The P-trap installs horizontally, and the U carve holds some water to moisture and keeps some water in the bowl.
If the toilet is not used for a longer time or infrequent flush toilet, it dries up the seal, which calls Water Barrier.
I suppose the bowl water is sucked out by a partial suction. A negative air pressure creates and by Gravitational force, it pulls down water enough energy to create suction as well.
Your toilet is working as an exhaust for the other plumbing. Now it seems the water barrier has dried out- as a result of sewer odor traveling around the house.
To Fix P-trap Problem
Use that toilet regularly, if it is not possible to flush it daily, two to three times.
Take one bucket of water and pour it directly into the toilet bowl. It automatically flushes down.
Do it for the next week. The water barrier has become normal, and the bowl does not empty at all.
