I am trying to upgrade from 23.10 to 24.10 by running update-manager. The GUI starts fine and says 24.10 is available and that I should upgrade. Clicking on the upgrade button results in a warning that my Ubuntu release is not supported.

it seems to work fine, though it only updates a few packages:
Hit:1 https://packages.microsoft.com/repos/code stable InRelease
Hit:2 http://security.ubuntu.com/ubuntu mantic-security InRelease
Hit:3 http://au.archive.ubuntu.com/ubuntu mantic InRelease
