Silver disk is the cover. Already removed two screws. The center light thing won’t twist or pull out. Just wanting to find and replace bulb.I'm confused (not uncommon). Is that silver thing the 'cover'? Or are you trying to remove the light unit from the side wall? It looks like there is a screw or two securing it to the wall. Did you remove it/them?

That looks like an LED so likely the entire assembly might need to be replaced. Did you take a volt meter and check for power to ensure it's getting 12 volts? Could also have adhesive or sticky back tape holding it in place. Good luck.
