(FIXED) Mesh renders in Scene View but not in Game View during play. Rebuilding prefab fixes problem

Unity Engine

2021.2.14f1

I have some prefabs with a mesh filter and mesh renderer component. The meshes render fine in the editor (scene view).
When I play the project, the objects render in Scene View, as expected, but do not not render in the Game View.
If I rebuild the entire prefab 1:1 from scratch, sometimes it goes back to working as it should.

Disregard. I’m an idiot.
