How To Fix “Login Failed. This Account Lacks The Required Entitlements” When Playing Fallout 76?

I wanted to know how good or bad this game is based on the current feedbacks from users and game reviewers. So, I created a Bethesda.net account and downloaded the client. Before downloading, I checked the game requirements and verified that my computer meets those requirements.

The game launcher installed successfully but when I started the game, this message appeared saying “Login failed. This account lacks the required entitlements”. How do I fix this?
