Unable to Activate GTA 5 on Rockstar Games – Activation Page Not Appearing

I purchased GTA 5 and have been trying to play, but I can't get past the activation process. I created a Rockstar Games account, completed all the necessary steps (email, password, nickname), but the activation screen simply doesn’t appear.

I've been trying since yesterday, following every instruction, but nothing works. I’m unsure if there’s an issue with the platform or my account setup, but I need help getting this activated so I can enjoy the game. Rockstar, please assist in resolving this activation issue.
