How to Downgrade Android 10 build 434 to pie stable Asus max pro m2

Star I

I want to downgrade my Asus Max Pro M2 android 10 to Android Pie, because there is a bug on my phone QKQ1.WW_Phone-17.2018.2012.434-20201203. Sometimes the phone crashes when moving files, the sound when listening to music sometimes gets bigger and smaller or unstable, the microphone too and sometimes the camera can't be opened or is dark.

Thank you for your help, so I can get the downgrade file  with the download link.
