Dear @Anone,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
Even holding an "Aufenthaltsgestattung" (during a pending asylum procedure) or with a Duldung, students may be insured in the compulsory insurance for students (like all students; § 5 Para. 1 No.9 SGB V) - usually up to the 30th birthday. Is the problem here that you are older than 30 years old? Unfortunately, I am not an expert in this field. But I highly recommend you to get help in a counselling office - maybe there are also support structures at the university itself? In the worst case you may have to accept a job which is not an official student job - but this dilemma should be solveable anyway.
I will also link my colleagues dear @mbeon-Éanna and @mbeon-fardeen here. Maybe they can add some advice/information.
All the best,
Meike
