Hard to say without more details. If you’ve got debt, I'd focus on getting a regular job for at least a year to pay off the majority.
One big advantage tech startups have is that you can build them from almost anywhere in the world. So I'd offer an alternative: move to a country where the cost of living is significantly lower and get a part-time job teaching English.
That’s what I did in my 20s, and it afforded me plenty of time to work on my own projects.
