I agree it should be PAM's job, but they don't seem to think so. From the
manpage for pam_fprintd:

   The PAM stack is by design a serialised authentication, so it is not
   possible for pam_fprintd to allow authentication through passwords and
   fingerprints at the same time.

   It is up to the application using the PAM services to implement
   separate PAM processes and run separate authentication stacks
   separately. This is the way multiple authentication methods are made
   available to users of gdm for example.

So maybe it is up to kscreenlocker to do the work, after all. There must be
some code in gdm that could be adapted in kscreenlocker and in sddm.

Yeah I'm pretty sure this is a PAM issue unfortunately.

I have the same issue on a fedora 38 beta.
After failing three times the fingerprint, I can indeed type my password to
unlock
It works the other way around: I can type my password, hit enter (nothing
happens), and then fail three times the fingerprint; the computer unlocks.
The problem might not be on kde side, as it is also present with other
programs.
For instance, if I use sudo, I need to fail three times the fingerprint before
being offered a keyboard prompt.

Can reproduce. Not sure if this is something we can fix on our side, or if it's
a PAM configuration thing.

FWIW you'll be able to use your text password if you try and fail to
authenticate with a fingerprint three times.
