frida.ProcessNotFoundError: unable to find process with name 'mediadrmserver'

I tested on Android Emulator google-play API 30 (Android 11) x86 and got error unable to find process with name 'mediadrmserver' (python script.py new):

Traceback (most recent call last):
  File "/Users/admin/Downloads/widevinel3_Android_PoC/script/script.py", line 100, in <module>
    main()

    session = device.attach(mediadrm)

frida.ProcessNotFoundError: unable to find process with name 'mediadrmserver'

Can you please check again and give some update? Thank!

It migh be because of the process name being mediaserver starting from Android 7. Use the option new with the script to search for it
