Unreal Engine 5.5 Dynamic Nav Mesh Not generating Instanced Static Meshes Spawned using Construction Script

In Unreal Engine 5.5 Dynamic Nav Mesh not generating on Instanced Static Meshes Spawned using Construction Script. Nav Mesh generates if I move the blueprint actor. But when I re-open the level nav mesh is gone again. Please check the video.

Everything works perfectly fine in Unreal engine 5.4 or previous versions.

Anyone having the same issue?

This issue persists, and it seems there hasn’t been any response to bug reports. It’s a game-breaking bug that significantly affects development. Could you please confirm whether the team is actively working on a fix? Any update would be greatly appreciated.

Hey there @Dazzling_Divine! Just to verify, using Runtime Navmesh, only instanced static meshes won’t be detected? Going to attempt to replicate the issue to see if I can determine a workaround in the meantime.
