Shedding, dying, or pests lmk

Thoughts? Is it shedding, dying, or pests?

Maybe it just had a long weekend. I've had toadstools stay closed for weeks so if you don't see any thing bothering it I'd leave it alone. if you see any AQuilonastra (asterina) starfish on it leave them be, they help it deal with shedding. See this post.
