Remove the loose screw and any debris.
Fill the hole with wood glue or epoxy resin.
Insert a wooden dowel or toothpicks into the hole for added support.
Trim the excess dowel or toothpicks.
Pre-drill a new hole slightly smaller than the screw size.
Drive the screw back into the repaired area carefully.
If the screw continues to slip, consider using a larger screw or a screw anchor.
