I had used the howdy for gdm,but passwod is error

I had used howdy for gdm,after the face recognition,I had type the password as usually,but it showed the password is error,I can not login in my system.
Did my password be changed by the howdy? And how should I do？

I've searched for similar issues already, and my issue has not been reported yet.

Linux distribution (if applicable):
manjaro

Howdy version (`sudo howdy version`):
2.6.1

Start by reviewing Howdy 2.6.1's GDM authentication behavior on Manjaro, focusing on the interaction between face recognition and the password prompt. Reproduce the failed login and verify whether the normal password is rejected only after face recognition; done means identifying the cause and documenting a confirmed fix or recovery path.
