What should I do?

Hi, I will start directly with my story, I have studied civil engineering in my bachelor’s and it was not my passion, I have graduated in Covid and did not work in engineering after that I moved to Germany to start masters in water and Environmental Engineering I am not satisfied at all specially masters in Germany are literally like bachelors only lectures with exams nothing practical in main universities I am almost 30 without career or experience or skills related to engineering I just pass with great marks What should I do ? I feel that my future is done
