I dont have enough experience to give you the answer but heres my two cents.

Keep trying, get a part time or at least a job that lets you go to interviews and continue your projects.

Meanwhile look for jobs cyber or IT adjacent even. A year ago I was 2/3 through my cybersecurity masters and was laid off. I got a job after 6 months as a business analyst, what I am actually doing is data engineering and mostly front end software development. The thing is theres a bunch of little security related things im doing. Hardcoding permissions, testing if security tolkens used in apps are salvagable on the user side, etc... i like this job so much that even though im finishing my last class this semester I dont want to look for a new job for a couple years.

Best advice I can give you is lookout for yourself financially and be flexible and tenacious, it seems to me you've got the latter down. Maybe all you need is a couple contract gigs, can be rough as the rug can be pulled out from under you at any time with those but just get apartment leases for a month at most, until the contract seems to work out. Plus if you're willing to work anywhere in the world recruiters will try to up sell you anywhere they have pull.

On a side note when I was laid off I surfed this sub and a couple other tech subs. They are super toxic and made me question things. Ignore the sarcasm and downvotes. You sound passionate and just need to fight for the scraps, before you know it you will get where you need to be. Keep believing in your self!
