If you're not in a good financial position, stabilizing your finances would be the first priority. I would focus on developing your professional networks and reaching out to past colleagues etc for job leads/referrals. You're at a stage where you've very little to lose and everything to gain from any interaction with reality/real-world problems.
Working on AI/vibe-coding, esp understanding the fundamentals, will be advantageous as everyone is still figuring things out. Your lack of experience won't hurt you as much, since no one really have any. Be careful with using too much AI assistance for learning, as it can actually slow you down and give you a feeling of compentency/productivity without deep understanding.
Good luck!
