Airpods pro crankling sound.

Its been a year since I bought my Airpods Pro. They didnt have any problems until this week. Whenever I use them in the noise canceling or transparency modes the right airpod makes a crankling noise and when using the noise canceling or transparancy modes, if i touch them to change the music or just adjust them, they just make a loud weird beeping sound or just crunching like sounds. I really dont know what to do and I hope that this is an software issue. hope that anyone can help me about this.
