My girlfriend is quitting her job without a backup plan

TL;DR: My (24M) SO (24F) that I live with is quitting her job without a backup plan, and I do not know what to do.
My girlfriend is a teacher, and is really committed to quitting her job after winter break. It?s a ton of weight on her right now and I think she/we would greatly benefit from her being in a low stress work environment. The problem is that because she got scouted by the school she?s at now during college (I?m assuming because of teacher shortages), she does not understand how abysmal the job market/job hunt is right now.
I keep insisting that it took nearly a year for me to even get a job in the career field I went to school for, and it can potentially take months just to hear back from a job listing. She has barely put any effort into creating a LinkedIn, has scrolled through a couple random job listings, and hasn?t applied anywhere yet plans to quit in like 2-3 months.
She has this idea that a job will come to her, and is really hooked on the idea of somehow making money through posting content on social media/TikTok, even though she hasn?t even started a public presence on there yet and she doesn?t know how it would work, and despite my insistence that very few people actually make money creating content online, and even if they do it takes them a LOOOOONG time to achieve that. She doesn?t even know what kind of ?content? she wants to make and yet is convinced she will be able to springboard to that after quitting her job!
She?s a big believer in manifestation and ?whatever I need will come to me?, which is great in concept but she hasn?t put in any of the effort to have those things come to her. I truly am trying to be as supportive about it as I can, but her attitude about all of it that has become honestly delusional and extremely frustrating. Frankly it?s also upsetting because her finances indirectly affect mine because we live together, and I can barely afford for myself to live so I will not be able to help her out in the slightest.
When I bring all of these concerns up to her she essentially says that she?s ?rebuking my doubting energy?, and turns into an uncomfortable disagreement or argument. I would absolutely love for her to follow her passions, but to me her lack of a plan is a recipe for destitution.
All of my rationalizing has done nothing to sway her mind, and she seems deadset on making this leap. Should I just keep trying to make her see reason? Should I just step back and let the chips fall where they may?
