Maybe try to get some other employment, literally any kind? Or yes, like others said, get help from friends, family, etc.
I’m not sure what your family situation is but if you don’t have a family to support, there are a lot of ways for a software developer to earn money on very short notice, maybe not great money but enough to live on. Keep networking and letting people know you’re looking for work and maybe even let them know you’re looking for significantly underpaid work until things get back to normal.
