There are a few potential causes for your PS4 freezing when playing Warzone, but the most common one is that you’re not using the correct settings. To fix this, follow these steps:

  1. Make sure that your PS4 is connected to the internet and that you have an active Warzone subscription.
  2. Go to Settings > System > Gaming > Warzone and make sure that “Enable Online Play” is checked.
  3. If you’re still having problems, try turning off background updates for Warzone and see if that fixes the issue. ..
