It's soaked and the wooden clip is cracked.

Fill the sawdust in the gap, and then use 502 glue.

There is nothing you can do about wood cracking. Put it in the vent to evaporate the water inside, and don't expose it to the sun. You can try filling the gap with sawdust and then bonding it with 502. After the furniture is air-dried, if the surface is damaged or scratched, you can add some paint of the same color, or you can apply bright paint and add a layer of protection.

Be careful not to expose the wood to the sun. The phenomenon of thermal expansion and cold contraction will lead to cracking and deformation in some places, the structure of wood will also be destroyed, and the supporting force is not as good as before. The correct way is to let the wood air dry naturally, and the dehumidifier can be used to speed up the air drying.
