ShapeCast2D fails to detect StaticBody2D immediately after re-enabling CollisionShape2D

Question

I’m dynamically toggling collision for a StaticBody2D by enabling and disabling its CollisionShape2D nodes through their disabled property. (Disabling CollisionLayers won’t work since a bug prevents Godot from clearing existing overlaps.)

When disabling the shapes, everything works as expected — a ShapeCast2D overlapping the body immediately stops detecting it when updated right away by calling force_shapecast_update().

However, when re-enabling the same shapes (disabled = false), the ShapeCast2D does not detect the body again right away. Even if I call force_shapecast_update() (deferred or immediate), the body remains non-collidable for several frames.

By updating the ShapeCast2D every frame and logging collisions, I confirmed that it takes multiple physics frames before the body becomes collidable again. Waiting just one physics frame is not enough.

Is there any reliable workaround?

Is it possible to wait until the first physics frame?
