Spawned objects not visible even though correctly spawned, after Meta Quest 3 headset update

I have been working on a MR project that uses the Meta SDK ver 67 with Unity 2022.3.24.

It is a game where insects are spawned on a tracked table in the room (space setup is done with only 1 table in the room).

Everything was working perfectly a few days ago suddenly when on Oct 3, 2024, the insects are no more visible. I have debugged in many ways and there are no errors, and everything is working as expected and insects are spawning in the build too - but just not visible.

Also, the insects are visible when I test it in the play mode in the editor with MRUK room prefabs.

I think it has something to do with the headset update as before Oct 3, I was facing an issue where my ray pointers from hands or controller were not showing that round cursor on the UI and was offsetting somewhat behind the UI, I guess. So, the day when the insect not visible bug came, this raycast issue was also fixed in the headset and I have not encountered it since.
