Perhaps for your own education the tip should have been that long list of conflicts. All those conflicts are because task-lxqt wants P6 packages where you seem to have P5 installed.
IMO no one should be installing ROME Plasma5. And when the next version of Rock is released no one should be installing Rock Plasma5. Plasma5 is over, as in EOL.
To be factual Plasma 5.27.11 was released 06 Mar 2024. It is still supported upstream and by OM. But practically speaking it is over. Plasma 6.1 was released 18 June 2024.
