Keepass KPUInput Auto-type stopped working after update to Fedora 43 KDE

I had set up the KPUInput Keepass plugin for auto-type according to these instructions. After an update to Fedora 43 KDE (from 42), the auto-type does not work. When trying to trigger it, the window is changed correctly, but no text is typed.

The uinputg group is still there, as is the /etc/udev/rules.d/89-uinput-u.rules file. I even recreated the KPUInputN.so plugin file according to the instructions, and re-copied the plugin files to /usr/lib/keepass and the KPUInputN.so to /usr/lib - no effect.

Any ideas are appreciated!
