> Same issue here, as a result of running `apt autoremove` on the 22nd February.

That doesn't sound like the same issue. The issue Adam encountered was that he manually removed cryptsetup-run because it identified itself as a transitional dummy package, and didn't notice that this also removed cryptsetup-initramfs from his system.

If autoremoval caused cryptsetup-initramfs to be removed from your system, that's a different problem.
