It can be believable reason if you squint, but why should you do the work for Marvel and explain why character acts radically different, instead of writers doing so or better yet, sticking to her character developement?
She really suffers from the lack of her own supporting cast. They were such a pleasant bunch in her run, and good influence on her.
Now she is turned into some thot that will chase after A-Listers and spout more memes in five issues than she did in her whole main series.
But hey, at least it's a sign she's popular in fandom now - She was taken away from her creator and given to diversity hire, who have no idea how write her in the form of miniseries (because they already know, that no one would consistently buy a full series, now that they booted Hastings out of it).
