Fedora 42 - LibreOffice 25.2.5.2 - Passwords all fail with incorrect password

I have two or three libreoffice files that I password protect. All has been well until this morning when I now get ‘Incorrect Password’ when trying to access the files. Any ideas what may have changed?

…my fault…
I tend to run ‘dnf update’ each day, but don’t reboot. So dnf must have updated some libraries or whatever that libreoffice uses for password control. As soon as I rebooted, the password mechanism worked perfectly again.
