why do you try uninstalling baloo and not just deactivating? you wouldn't have to reinstall but just rolling back, via eopkg hs -t <history number>
can you please run sudo eopkg it --reinstall elisa khotkeys plasma-desktop plasma-browser-integration kde-cli-tools gwenview baloo-widgets powerdevil dolphin systemsettings plasma-workspace baloo
to get really everything back. Did you install anything additionally? Because that error tells you to add these env to your .bashrc inside your userfolder and relog
