Dear @khanbaba,
Welcome back to the Wefugees Community and thank you for your question!
Indeed, as also "Handbook Germany" state on their website, the BAMF is deciding again on asylum applications of Afghan nationals since the 1st of December. Therefore, you may receive a letter from the authorities anytime. Please follow the link for more information (also Farsi and Paschto).
Fingers crossed for your application and all the best,
Meike
