Brexit Permit Renewal and studying in Germany

Hello, I arrived in Germany before Brexit to originally work freelance as a teacher. I then decided to study for a PhD which is not yet completed and I am between jobs. I decided to take a student job to concentrate on studying more which expires in January. However, my 5 year Brexit permit is up for renewal, and the next renewal should be for 10 years as I have been living in Germany since 2017. However, I am scared that my application for renewal will be rejected because I may have no job and as I have student status I am not elligible for job seekers. I am close to the end of my studies so I doubt that they will want me to swap to a student visa. I hope you can offer me advice, as to whether I will still be able to get the Brexit Bermit renewal as I have been living here for so long. For extra information, I am partly self taught in German from work so do not have an offical B1 certificate in German. I hope you can offer me some advice.
