Meshes Disappearing when pressing play

Hello!
For whatever strange reason When these meshes were reimported they just abruptly stopped showing up when I hit play in studio or play the actual experience.

I am not too certain why this is happening… Does anyone have a clue as to why this might be occurring?

Here are the meshes inside ROBLOX Studio.

As you can see they disappear when pressing play.

This is really frustrating so if anyone could give me any hints towards fixing this that would be very much appreciated!
Many thanks,
Shark

Nvm… randomly started working…
