Gura got tired of effortlessly mogging everything and everyone in anything she does and it's what turned her into the lazy, nihilistic shark she is now. Think about it. Before hololive she was a 1m youtuber simply because of some silly boomer meme song she made, then she "restarted" as Gura and gained even more subs because she instantly became a meme again. Everything she touches turns into gold with no effort on her part, all her good qualities and talents are things she was simply born with, and she's never had to work hard for anything in her life yet still mogs all the tryhards who make achieving what she already got their lifes work.

>inhuman charisma so strong it's practically hypnosis and just causes everyone to unconditionally love her

And she knows it. She probably realized the absurdity of it all and it became too cringe for her to continue putting in any effort into her streams and not starting any projects such as producing a song. She probably in some self-hating way even enjoys that her model is the worst one.
