Way too long op. You should have shared the important details only though I ended up reading your story anyway. It's basically a failed business story which is pretty common in the world that we live in.
Instead of relying on funding campaigns, I advise trying to get back on your feet on your own because that will help you in the long-term. Rely on yourself instead of trying to rely on others op.
I am sharing this advice based on personal experience. This helped me improve greatly in many aspects in the short-term and long-term.
I agree with you he already created good projects in the past he can do this again he has the skill to do that, employ yourself there are other companies who will need your skill why rely on crowdfunding be self-reliant, you are still blessed for having your skill and healthy, there are other people who get CoVid and everything on them are wiped out, count your blessing you can still get up
