Rigged cloth disappears

I have a rigged cape on my character, on which I’d like to add cloth physics. However, whenever I try to add the cloth component, the cape becomes invisible. More specifically, any section of the cloth which isnt constrained to not move disappears. Anyone know what the problem might be?

What tests have you performed so far to attempt resolve?

What happens on a ‘fake’ cape that does not have rigging?

Where is the cape located in 3D space when applying the cloth component?
