For me, what did it is that I needed to make sure that the account used to purchase the app I was looking for, was the exact same account used for Google Play. I was using it to purchase a Premium license for an app, and when creating the account for that app, I was using a different account that didn’t match my Google Play account that I had entered via Bluestacks. That resulted in me getting this error. I then tried login in Google Play using another Google account, and used the same account to buy my license, and it passed without any issue.
