Layout randomly making one object transparent

Lately, some (usually only one) object becomes transparent in Layout views. When I double click the window to modift the scene, it returns to normal, but as soon as I click off the window, it turn transparent again. I have tried deleting the compnent and redrawing if from scratch, changing textures, changing styles, none have any impact. I am using Sketchup Pro 2023.

Any help would be greatly appreciated.
