Relaunch Warzone and Battle.net Launcher

Perform a Cold Restart of the System/Device and Networking Devices

Change Calling Card of the Player for the Warzone Game

Disable Crossplay in the Warzone Options

Restore Licenses on the Play Station

In such a case, you may fix dev error 5476 on PS5 or any other Play Station by restoring the licenses on the console.
Try Another Network
The issue could also be a result of your ISP’s restrictions that limits the communication (as the communication might be marked as malicious due to a false positive in the ISP filters) between Warzone and its servers. In such a case, trying another network may solve the problem.
Rebuild Database of the Play Station
You may get dev error 5476 Warzone on the Play Station if its database is corrupt. In this case, rebuilding the database of the Play Station may clear the Warzone dev error.

Scan and Repair the Warzone’s Installation
This error might also occur if the game’s installation is corrupt due to a partial installation of the latest update. Here, repairing the game’s installation through its launcher may solve the problem.
Change the Security Permissions of Warzone/ Battle.net App
If the Warzone and Battle.net app does not have the administrative privileges to access the protected system files or resources, then that could result in error 5476 of Warzone. In such a case, changing the security permissions of the Warzone/ Battle.net app to administrator and deleting the files in the game’s data folder may solve the problem.
Reinstall the System’s Graphics Driver
You may encounter dev error 5476 if the system’s graphics driver is corrupt and its inability to parse the game’s graphics may crash Warzone. In this case, you may fix Dev error 5476 by reinstalling the system’s graphics driver. Before moving on, make sure to download the latest graphics driver from the OEM (PC OEM like Dell or graphics device OEM like AMD) website.
Modify the Warzone Installation
If any of the game’s mods are not compatible with the game, then it can lead to the dev error 5476. In this case, modifying the Warzone installation to remove the game’s mods may solve the problem.
Reinstall the Warzone Game
If none of the above cleared the dev error 5476, then the issue could be a result of the corrupt installation of Warzone that did not get fixed after repairing the game’s installation. In such a scenario, reinstalling Warzone may clear the error under discussion. Before moving on, do not forget to backup the Warzone game data like screenshots, etc.
