Summary
When using a Switch Device to toggle between two custom static meshes - one with BlockAll collision (ON state) and one with NoCollision (OFF state) - the collision persists even after switching to the OFF state. This results in an invisible, impassable barrier.

Steps to Reproduce
-
Place a Switch Device in the world.
-
Set up two custom static meshes:
-
ON Mesh: a hollow cube with
BlockAllcollision -
OFF Mesh: a hollow cube with
NoCollision
-
Configure the Switch to toggle between these two meshes.
-
During gameplay, toggle the switch from ON to OFF.
-
Attempt to walk through the area where the mesh used to be.
Expected Result
Toggling the switch OFF should swap the custom mesh to the one with NoCollision, allowing players to freely pass through the space.
Observed Result
After toggling the switch OFF, the custom mesh becomes invisible as expected, but the collision from the previous ON-state mesh remains. The player character collides with an invisible impassable barrier, causing jittering, unintended interactions, and navigation issues.

Additional Notes
- The issue appears consistently in both live and preview sessions.
- The mesh visibly swaps correctly, but the collision is not cleared.
- This renders Switch Devices unreliable as a replacement to the currently broken Barrier Devices.
This bug prevents creators from using Switch Devices with custom meshes as an alternative to the currently broken Barrier Devices. As a result, essential gameplay areas remain inaccessible, and multiplayer sessions are significantly disrupted.
