I do have a backup of the private key, but it’s 1. out of reach at the
moment and 2. it’s a pain to restore. So far, I’m still optimistic that
the sender will eventually provide me with a message that I can decrypt.

Thanks a lot for your explanations!

PS: I’m toying with the idea of switching from my smart card to a Trezor
hardware token. This would mean generating an entirely new key (only
256 bit ECC supported). OTOH there are several advantages such as the
Trezor being a well documented open source device, and – of course – its
size with integrated key pad solution. It also depends on whether I can
get either a smart card reader or the Trezor to work with
