Black Ops 6 DEV Error 5820 troubleshooting on PS5

Quick answer: DEV Error 5820 is not currently defined in Activision’s public support pages. On PS5, restart the game and console, update Black Ops 6 and system software, restore the game’s license, then clear the PS5 system cache. Treat these as safe troubleshooting steps, not a guaranteed code-specific cure.

Before you start

  • Check Activision Online Services for an outage.
  • Do not delete saved data or reset the console.
  • Make sure the console has free space for game and system updates.

Try these fixes in order

  1. Restart the game and PS5: Close Black Ops 6 completely, restart the console, and try the same mode again.
  2. Update Black Ops 6: Highlight the game, press Options, and choose Check for Update.
  3. Update PS5 software: Go to Settings > System > System Software > System Software Update and Settings.
  4. Restore the license: Highlight Black Ops 6, press Options, and select Restore License. Alternatively use Settings > Users and Accounts > Other > Restore Licenses.
  5. Clear system cache: Turn off the PS5. Hold the power button until the second beep, connect the controller by USB, choose Clear Cache and Rebuild Database, then Clear System Software Cache.
  6. Check installed game content: Open Manage Game Content from the game’s Options menu and install any missing required pack.
  7. Reinstall only as a last resort: Delete and reinstall the game application, not saved data.

Why this may work

Activision recommends current console and game software for BO6 crashes. PlayStation says restoring licenses can help when a game crashes and does not affect data. Clearing the system cache removes temporary console files without selecting the destructive reset options.

Alternatives

  • Try another BO6 mode to determine whether the fault is mode-specific.
  • Stop if Activision reports an incident and retest after service recovery.
  • Contact Activision with the exact code, timestamp, mode, and PS5 software version.

Warnings and reversal

In Safe Mode, select Clear System Software Cache only. Do not choose Reset PS5 or Reset PS5 (Reinstall System Software); both delete user data. Restore Licenses does not need to be undone.

FAQ

Is DEV Error 5820 officially documented?

No current Activision support article defines this exact code, so the cause remains unconfirmed.

Will Restore Licenses delete saves?

No. PlayStation states that license restoration does not affect data.

Is clearing the cache the same as resetting PS5?

No. They are separate Safe Mode options. Choose only Clear System Software Cache.

The video and viewer feedback point to license restoration as a low-risk step. Because the exact code is not documented, this guide labels the method as an unofficial, situation-dependent workaround and adds current Activision and PlayStation checks.
