New updates are being added at the bottom of this story…….

Original story (published on April 29, 2021) follows:

Fallout 76 has been quite popular ever since it came out on Microsoft Windows, PlayStation 4, and Xbox One in November 2018.

However, issues like Fallout 76 crashing and the unknown error message can spoil the user experience.


So, let’s take a look at the official workarounds to fix the crashing issue on PC, PlayStation 4, and Xbox One along with the unknown error message fix.

Fallout 76 crashing on PC

The first step to fix the crashing issue on PC (Microsoft Windows) is to check whether the latest AMD or Nvidia video card drivers are installed.

After that, ensure that Fallout 76 is being launched with administrative privileges. If the issue persists, open the Bethesda.net launcher and select Fallout 76 then go to Game Options and select the Scan and Repair option.

Also, Steam users can verify the integrity of game files by opening Steam and heading over to Library. Once done, open Fallout 76 Properties by right clicking on the game and switch to the Local Files tab and select the Verify Integrity of Game Files… option.


Crashing on PlayStation 4

PlayStation 4 users have to restart the game by pressing the PS button on the controller and heading over to Dashboard. After that, open the Fallout 76 Options and select Close Application then press X on the controller.

Now, select Yes and press the X button on the controller again. Once done, select Fallout 76 and press X on the controller to restart the game.

If the issue persists after restarting the game, head over to the next step for power cycling the console.


Power cycle PlayStation 4 by pressing and holding the PS button on the controller. After doing so, select the Turn Off PS4 option and unplug the power cable for 10 seconds once the light on the console switches off.

Plug in the power cable and switch on the console by pressing and holding the PS button on the controller.

If power cycling does not address the issue, check out the next step for clearing the save data.


Clearing the save data will not affect the game progression or character data but will remove photos from the Photo Gallery so make sure to back them up on the PlayStation cloud.

Once done, go to Settings from the PlayStation Dynamic Menu and select Application Saved Data. In this section, go to the Saved Data in System Storage option and select Delete then select Fallout 76 by checking the radio box next to it.

Now, delete the save data by selecting the Delete option on the bottom right then selecting OK.


In case all the steps given above do not resolve the crashing issue on PlayStation 4, uninstall the game then reinstall it.

Crashing on Xbox One

Users of Xbox One also have to restart the game by pressing the Xbox button on the controller returning to Home Screen. After that, close the game by pressing the Menu button on the controller and launch it again.

If the issue persists, power cycle Xbox One by pressing and holding the Xbox button on the console for 10 seconds. Now, unplug the power cable for 10 seconds then plug it back in and switch on the console by pressing the Xbox button on it.

Also, make sure that the console is running the latest software update from Microsoft in case the above steps do not work.


After ensuring that the console is running the latest software version, proceed with clearing the save data after backing up any saved photos.

To clear the save data on Xbox One, open My games and apps from Home Screen and select Fallout 76. Now, press the Menu button on the controller then select the Manage Game option.

Once done, scroll down to the Saved Data section in the menu on the left and select the saved data for the gamertag to be deleted then press the A button on the controller. Now, select the Delete from everywhere option to confirm the deletion.


In case none of the steps given above work, proceed with uninstalling and reinstalling Fallout 76 on Xbox One.

Fallout 76 unknown error message

Players may get the ‘An unknown error has occurred [4:7:0] – Error Code’ message at times which may prevent them from playing the game.

This message usually appears when Fallout 76 is not launched using the Bethesda.net Launcher or if users are not completely signed into their Bathesda.net account.

So, the said issue can be fixed by verifying the Bethesda.net account login and launching the game from the Bethesda.net launcher.


That said, if you are facing crashing and unknown error issues with Fallout 76, be sure to follow these official workarounds.
