Download the downgrade version of Android 9 from the Asus website and install it through Fast boot mode. Note there may be a data loss while downgrading , So make sure to take back up.
I tried but it did not. I tried 3 times failed.

Also, please provide me if there's any issue detail you're facing in Version 424. Thank you.
Thank you for the answer. I downloaded it to .63. Everything is good.
When it comes to bugs in version 424, the earpiece and speaker sound is very low, and fast charging doesn't work.
Thank you. This method worked
