Unsolicited advice: Try to get someone to review your resume and other materials (grades, cover letters, recommendation letters, official documents, etc). Ideally by someone like a recruiter, the schools career center if there is one, or even just a personal friend. Preferably someone with recent experience.

No judgement, but you might be missing something or doing something "wrong" without knowing it. Being ghosted absolutely everywhere sounds strange regardless of how the market is doing. CS as a field is not dead yet.

As for the field not caring about you: nobody owes you anything. That doesn't mean you should just roll over and give up. And it also doesn't mean you should take shit from abusive managers "working you to death". There are good people and companies out there, but you need to go out and find them. I work only 4 days a week, prioritize my family, and my employer accepts that.

Compared to so many other jobs CS is still a lot better than other options and will continue to be viable for a long time. You're absolutely not too late.
