Sorry to hear that. This info does make it easier to rule out some options.
As a hiring manager, I'm usually not looking for a specific skillset from recent grads, but whether they are competent learners and have good communication skills. Both of these attributes means they can quickly adapt and more likely to contribute (or at least be less of a burden in the short run).
From your other posts, I'd recommend you work on your writing (English and your local language) to be more professional. Don't use AI writing, as you'd lose your writing "voice" and others will judge you for it.
For networking, I'd reach out to senior engineers in your area or prior companies to ask for advice on what's important to learn that you didn't learn in college. Don't ask for a job, as that could send their guards up. Follow through with their advice and update them regularly, every few weeks. The goal would be to show them you're a quick learner and can communicate well. They're more likely to recognize an opportunity and send a lead your way. It may not be with their current company, but a friend's company etc. Many jobs are shopped around informally via vetted social relationships before being shown in public.
If you're really strapped for $$, taking on any tech-adjacent job could be useful, including customer support roles where you can practice your communication skills.
