We have a fix here in the pre-release (1.9.20). Could you try it out? Tested with my SeedSigner and was able to scan the XPUB.

> Have you tried the fixes suggested in that GH thread?

libssl1.1 isn't available in the debian repos for bookworm or testing so It won't be easy to install, if I have some free time I can look into it.  libssl1.1 is pretty old though, Nunchuk should update to use a newer version IMO.
