Hey @jibon57 ,
Can you try installing the latest CLI version - 4.2.1 - it contains a fix for a similar case - the tns run android command fails in case you do not have Android Virtual devices: https://github.com/NativeScript/nativescript-cli/releases/tag/v4.2.1

Can you give it a try and see if it resolves your issue?

Thanks @rosen-vladimirov. I am confirming that 4.2.1 has solved my problem :)
