fprintd: Failed to start Tudor host process <...> NoReply: Remote peer disconnected

[VeryEvilHumna]

I have 06cb:00be and experienced the same issue as described in #35. After 1d08e98 commit is made I git-pulled the repo and tried to reinstall everything as described in readme.

My environment is ThinkPad L15 Gen 1 with Fedora 41, libfprint-tod is from quantt corp repo

dnf list:

Also, unrelated, but ninja install script moves libtudor_tod.so to /usr/local/lib64/<...>, but libfprint-tod checks /usr/lib64/<...>, so I moved libtudor_tod.so to /usr/lib64/libfprint-2/tod-1/, maybe install script needs a fix
