Hey there @harshjeet.
As far as I reckon, the issue you are facing is due to the binder kernel module not being mounted.
I have covered all of this in detail in my guide.
I would suggest undoing everything you have done to install anbox from other youtube videos and start with this guide linked below from the beginning.
This guide created has been created with newcomers in mind, especially someone new to the command line.
@SGS could reopen the anbox thread, as I have updated it recently to account for the latest changes.
