Not sure what more there is to say.
Get the same signing key you had when you first uploaded it and use that to sign your APK.
If you have lost the original, you need to make a fresh Android title with different bundle identifier.
If you enabled Google Play Signing then you can recover it from Google:

I followed the youtube tutorial I created a keystore in unity and also enabled google play signing key. Is that costing the problem? After I try couple times than I created another keystore in unity again. So now should I just ignore the keystore that I have created just use google play signing key?

Yeah, I just checked and it IS different now. It has recently changed so that Google assumes that you will enroll for key signing by default. You need key signing to do AAB, and they want everybody to use AAB instead of APK. But APK is necessary for deploying locally to device so things have indeed changed.
