shw, welcome.

Two things immediately come to mind; the first is that it's just old leaves dying, although unless you haven't repotted in a *very* long time and have many rows of leaves, it's less likely than the second thing; root rot.

Pull the plant out of the container and look for light-colored, firm roots. Smell the soil; it should smell fresh and earthy -- if it's sour or rotten, you have trouble. Also, check the main stem; scrape the surface with a fingernail; it should be green and juicy underneath; if it's brown and/or dry, you have an advanced case and will have to re-root the crown.

I wouldn't wait on this; root rot can kill your plant in a surprisingly short time.

Good luck and let us know how it goes.

Hi,
I would remove the dying leaves, cut off some of the bottom of the plant if you have a neck and repot it in clean fresh soil.

I had a couple chimeras do this. i have an Alps now that has only 3 leaves left but it is forming suckers around the main trunk of the AV and they look in good condition
