This didn't happen to me in elementary 5.1.6, but it is happening in elementary 6 Odin (same system/hardware). I can't seem to lock my system on elementary 6 (latest updates installed) using the GUI or the keyboard, so I killed wingpanel and started it back up and get the following:

sudo /usr/bin/io.elementary.wingpanel

(io.elementary.wingpanel:26935): wingpanel-WARNING **: 14:11:49.566: Application.vala:46: Failed to register with Session manager

and then when I try to lock via the GUI I get:
