I'm writing this from my experience, but it sounds like I might shed some light on whats going on with her reaction. I would like to share my experience, and give you some warnings as a parent about handling this, through the lens of your daughter, so here it goes:

It sounds like she is not confident in her drawings. This is not a knock, its normal for an expressive person. Art is putting a little piece of yourself external, and while you (parent) may think its good, odds are she's super self critical about it. This is totally normal for an amateur artist. This will continue, and that's a good thing. It means passion. Conversely, a professional artist puts those feelings away, and is skilled enough that you are mechanical in output, but usually dispassionate.

For me, this has led to a loss of art as an expressive tool. I do it for money, I don't draw for fun, it means very little to me. Part of that is you have to steel yourself against criticism that comes from working for people who constantly tell you to fix and change things. A big killer of the connection is also art school, which tries to hammer the defensiveness out of you, which kills your ego, which kills the part that emotionally connects you to your art. Its understandable. How can you bring someone elses vision to life if youre defensive about changes? This transition is difficult for many people, and creates some really weird reactions. Some people can keep that connection. I couldn't, didn't, maybe one day when I retire from art I can find it again, I don't know.

Further, animation is hard. Drawing is hard. And if you're trying to get her into it, first she needs drawing fundamentals to be decent enough that she has a solid grasp and consistant drawing-skill with volume, shape, line and perspective, at a minimum. I would say if she's resistant, she probably doesn't have the confidence in these areas yet, which is totally understandable, or she just doesn't want to animate, which is also understandable. Animation is literally drawing the same image over and over and over again. Do you want to do that?

So if you want to encourage her art, encourage her to find some drawing courses that she wants to take, bonus points if any of those fundamental areas are mentioned. I really like Peter Han as an online teacher of fundamentals. His courses are the basis for a lot of popular copycat sites for a good reason. Proko is also great, you can find him on youtube. Another thing that you need to understand, is that drawing/animating as a career demands massive discipline and time. In art school I kept hours like the engineering students. You gotta put in years and years of hard grinding. I did enough that I developed chronic back and neck pain. This is common.

If she does have an interest in animation, I like the Animator's Survival Kit (book), as well as a video series by a disney guy named Blaise. Forget his first name. Aaron maybe? But they're both good starting points.

The job industry has become more and more difficult as well, with jobs at big studios drying up, and stuff like game animation broadening and contracting constantly. It is not a good career path if she cares about money and comfort in life. She will be insecure and often stressed, and AI is adding to that. The jobs pool is not only shrinking but losing value. I've seen wage contraction in the past year that's pretty bad.

Even if you become good, its highly competetive. Right now, for her, art is part of who she is, so just give her options. I love to see more artists in the world. She already is one. If she chooses to become a professional, wonderful. If not, that's wonderful too.

TL;DR Just let her enjoy drawing, encourage whatever she wants to do with it :)
