I have found a workaround that kind of works ... The problem is with the sane library, so it has to be downgraded. I restored /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.0.27 from my previous Ubuntu 18.04 installation and linked it instead of the current version, and that's all, it works for me in Ubuntu 21.10.
