Why won't it let me play battlefield 6

Well first, you have not done your homework. And even if you had done, its too late in the night for you to play now anyway. You can play tomorrow.

Hey lakp4a7vku1v​, 

Sorry to hear you're not able to play right now. Are you getting any error messages? What's happening when you try to launch the game?

If you've tried any particular troubleshooting steps already, let us know so we're not suggesting anything you've tried before. Any other details you can share about what you're seeing can help as well, thanks!
