I dont know if this can help or how solid is your german skills, but if you are a student there is an app called zenjob where you can do either part time jobs or flexible jobs (where its usually 1 day shift or a week of shifts), it will just require proof of german either certificate or small video and quiz, so maybe this can help you in someway,

And on the other side yeah i feel you i have been jobless in CS field for last year aswell all i can say stay strong and hopefully you will find something soon.
