Luckily, the fix comes from PlayStation itself, as the company uploaded some troubleshooting tips to its website. So your best bet in addressing this issue is the following steps:

  1. Close the application, install the latest System Software and game updates, and restart the system.
  2. If you have upgraded the Hard Disk Drive (“HDD”) in your system, please re-install the original HDD.
  3. If the error occurs again, back up your saved data, and then go to [Settings] > [Initialization] and choose [Initialize PS4].
  4. If the error occurs with every application, or as soon as the application starts, please contact PlayStation Support.

For those experiencing this in Warzone, it’s being classified as “an error has occurred in the application”, which means that it ultimately could fall on Activision and/or Infinity Ward to fix it.

The good news is that Activision have already acknowledged the sharp increase in system crashes following the Season 6 update, so a fix could already be on the way.
