I think a good place to start is stepping back and trying to remove some of the labels you've put on her. This sounds like a very anxious, insecure dog who's overwhelmed and doesn't understand what's expected of her, not resentful or spiteful or jealous. It can be helpful to realize that she's not acting this way because she's trying to be difficult, but because she's just freaked out and doesn't know what else to do.
Have you worked on helping her feel like her crate is a safe, calm space rather than a punishment? Knowing she can stay in her safe crate and be comfortable and happy and unable to destroy anything could help a lot here. The frantic pawing and humping screams 'overwhelmed, stressed dog' to me, so using the crate as a cool-down space where you offer relaxing enrichment instead of a prison cell where she's being punished might be more effective. Start freezing all of her meals in Kong-style fillable chew toys, so that she spends a lot more time daily chewing and licking. Chewing is naturally calming behavior for dogs, which she could definitely benefit from. If you have several a day, you can give her one in the crate when she gets worked up like this to help her learn that she can manage her stress though an appropriate outlet like chewing her Kongs or other chew toys/edible chews.
I'd also commit to doing some low-pressure, fun training with her every day. I'm talking easy behaviors and cute tricks. Stuff that you can keep short, reward-based, and positive for both of you, so you can hopefully start building a bond and better understanding of how to communicate with each other. Touch a target with her nose or paw, spin in a circle, give her paw, that kind of thing.
This may be a dog who will benefit from anti-anxiety medication. Ideally you'd have a behaviorist or veterinary behaviorist evaluate her and help you make that call, but your regular vet may be able to help you as well, or even do a phone consult with a veterinary behaviorist on your behalf for less money than an in-person appointment would be. It'd be worth calling your vet practice and asking about the options with that. Be up front about the money issues - most vets understand that their clients don't have unlimited funds and appreciate that you're trying to find solutions that won't bankrupt you.
Similarly, you can check organizations like the Certification Council for Pet Dog Trainers (Certification for professional dog trainers and behavior consultants) or International Association of Animal Behavior Consultants (International Association of Animal Behavior Consultants), which both have a 'find a certified behaviorist near you' function, and price out what a single remote consult would cost. Prices vary a lot by region, but many trainers and behaviorists are doing way more work through online video services these days due to the pandemic, so you may be able to find someone within your budget who will talk to you for 40 minutes-1 hour and set up a basic plan. You'll have to be committed to enacting that plan on your own, but a single consult like that is more affordable than paying for regular hands-on guidance for multiple weeks or months.
