Welcome back to the Wefugees Community!
With my last reply, I sent you a link (https://www.returningfromgermany.de/de/centres) for a search engine for counselling offices specialized on voluntary return. Did you find a respective service and were they able to support you?
Being enrolled in a voluntary return process normally includes, that participants do not receive an entry ban. But based on the few information you shared, it is quite hard to assess your individual case.
I would recommend you to contact a respective counselor which might have a better knowledge of the program, services and conditions.
All the best,
