The Queen is still trapped in a Crystal, to be fair. So it's not like she could really do much outside of talk. Still a not great environment to be stuck in for an extended period though, considering how ruined Kirakiland is, but fair point.
And she was absolutely just trying to avoid Uta being hurt by discovering Purirun had forgotten her. She was being considerate, and mostly improvising. She wasn't the most pleased to see Uta in Episode 20, sure, but she did nothing to stop them from having a picnic with Purirun. She told them to stop trying to restore her memories, because she thought it was hopeless, but she never stopped them having the picnic. If she was truly trying to keep them away from each other out of some malintent, she would've been against the picnic the whole time, including throughout.
I'd say, if anything, the worst thing that she did is maybe steal Tanakaan's house, but considering that it was primarily to give Purirun a roof over her head and food to eat, it's fair enough (And Tanakaan clearly didn't mind in the end, considering the circumstances).
