Screen sharing via DWService fails

Running a fresh install of Fedora 36 KDE.
DWService initially threw an error about XWayland, so I switched over to X11, which I have verified I’m running. That Wayland error went away and now I get a more generic “Error: Session not started.” Or the more confusing: “Error: ‘NoneType’ object has no attribute ‘release’”

DWService works in every other respect. I previously had it fully working on Fedora 36 Gnome on this laptop. Does anybody here have any experience with this or suggestions about what I might try? Thank you.
