'Failed to Launch Game: An Error on Our End' for Multiple Games. Any Fixes?

Hello everyone,
Are you currently experiencing problems launching your game?
Here are some solutions that might help you.
This post helps avoid duplicate posts with the same problem.
In this post, we will only address the error “Your game failed to launch or "000005 error” As well as simple and non-advanced resolutions. 

Before making any changes to your PC, you must first check whether the problem can be resolved using the “EAAntiCheat.Installer.exe” tool available here: https://cdn.eaanticheat.ac.ea.com/EAAntiCheat.Installer.exe 
 Follow the official steps: https://help.ea.com/en/articles/platforms/pc-ea-anticheat/ 

Is your problem still unresolved despite the official advice ? 
I'm here to help. The solutions will be sorted by category (nvidia,amd...)

Remember to disable your background applications before starting the tutorial. I would also like to point out that  MSI Afterburner and Rivaturner software are not compatible with anti-cheat software.

NVIDIA GPU
This category should only be followed if you have an Nvidia card*

First solution ; Restore driver setting

After that, start your game.

Second solution ;  Install version 577.0 of your NVIDIA driver. 
(NOTE: As I mentioned, these are simple repairs to help novice users. If you are an advanced computer user, uninstall using DDU)

Go to the Nvidia driver website and install version 577.0 (after specifying your graphics card; if you don't know your graphics card, press Ctrl + Alt + Del and select “Task Manager” Click the “Performance” tab and select “GPU” in the left navigation panel > https://www.nvidia.com/en-us/drivers/ 

After installation, open it and proceed with an advanced installation, then select “perform a clean installation”

Once the installation is complete, restart your PC and launch your game.µ
After that, launch the EA Javelin anti-cheat installer available here > https://cdn.eaanticheat.ac.ea.com/EAAntiCheat.Installer.exe 
And click "Repair"(A page will open, and all you have to do is select the installation folder of your game)
Then launch your game.

AMD GPU
This category should only be followed if you have an AMD card*

(NOTE: As I mentioned, these are simple repairs to help novice users. If you are an advanced computer user, uninstall using DDU) Make sure you have the latest version of the AMD driver via > https://www.amd.com/en/resources/support-articles/faqs/GPU-131.html 

First solution ; Disable AMD optimizations for Battlefield 2042

- Disable AMD optimizations for Battlefield 2042 via the AMD Adrenalin app, available here > https://www.amd.com/fr/products/software/adrenalin/software-performance.html#download

Once in the application, go to the "gaming" tab, select your game “Battlefield 2042” and disable all optimizations related to the game as shown in the image.

After that, start your game. (Thanks to H4RP33R​  for this solution)

Second solution ; No other solution for AMD has been registered; for now, the first solution still seems to be working.

The game still doesn't work after doing all that ?

Your problem may also stem from your Windows updates, which can sometimes cause corruption and licensing issues. I should also point out that this does not happen for all users; sometimes updates do not cause any problems.

First solution : Uninstalling Windows updates that could cause the problem
For now, here are the updates causing problems: KB5063878 - KB5064081

To uninstall these updates, follow these links:
Windows 10 > How to uninstall a Windows Update (windows 10)
Windows 11 > How to uninstall a Windows Update (windows 11)

After uninstalling the update, restart your PC.
After that, launch the EA Javelin anti-cheat installer available here > https://cdn.eaanticheat.ac.ea.com/EAAntiCheat.Installer.exe 
And click "Repair"(A page will open, and all you have to do is select the installation folder of your game)

Then launch your game.

Second solution : Clear cache

--EA app--
If you're using the EA app, perform an app recovery (the app will restart), then “repair” your game.

--Steam--
If you use Steam, go to the Steam settings in the “Download” tab, click “Clear Cache,” then repair your game (on Steam, this operation is called “Verify Integrity of Game Files”).

Then launch EA app and Steam in administrator, after full launch, start the game.

Third solution: Disable the EA App overlay

As I mentioned above, these are only simple solutions that do not involve using CMD. Other simple solutions will be added along with advanced options.
