Thank you for reaching out to us again!
I can see that you asked a very similar question before and can't add much more to Thorgen's reply (How can I get a residence permit for Germany if I have a child with a British woman?)
In order to apply for an Aufenthaltserlaubnis/ residence permit in Germany through your child, it would first of all have to have a residence title or German citizenship. You would also need the "Sorgerecht" (shared legal custody) of your child and the "Vaterschaftsanerkennung" (acknowledging paternity).
I assume that your girlfriend has a residence permit based on her job, so your child has one too. Therefore, if I'm not mistaken, you could still try and get a residence permit through your child. Please note that it's not guaranteed!
Also consider reaching out to a refugee support center, where you can share your story in detail. They will have tips where to go and how to apply (if possible), or share other options you have.
Here is a Berlin service website explaining how to apply: https://service.berlin.de/dienstleistung/305289/en/
And here are some support centers (please choose the region): https://www.proasyl.de/en/our-network/
I hope this helps. Feel free to reach out to us again if you need any further assistance.
