"Fatal error!" After update, crashes on launch every time

[EnVenta]

This game worked fine a week or two ago, but after this most recent update, it now crashes immediately with a tiny popup that says 'Fatal error!'

Did all the usuals: reinstalled game, updated Windows, updated Geforce. Same results.

What's going on?

Run the Steam program to check and correct your game files integrity. See the below Steam link which may be helpful to resolve the problem.

Thanks for the suggestion. Tried the fixes mentioned to no avail.

Also, I just got Sengoku Dynasty today -- toplitz's next Dynasty installment -- and it has the same problem! It's actually why I noticed that Medieval has this issue is because I wanted to make sure that Medieval still worked like it did a couple weeks ago. Nope, same crash.

I'm having the same issue and the fix didn't work for me either.

The fatal error unfortunately is tricky to determine, but usually a corrupt driver or .dll.

Possible solutions:

Update your Unreal Engine 5.
Update your GPU driver.
Verify the installation.
Stop overclocking.
Change your default graphics card.
Repair your system files.
Disable your antivirus temporarily.
Perform a reinstalling.
Force the game to start with dx11 argument in Steam client ( -dx11 ).

Hello

I have 2 computers, using the same steam account.
When I launch the game using steam interface on one computer I have the "UE4 fatal error" message and on the other one the game launches properly
All drivers are up to date on both computers
DX12 is selected
I tried to solve the problem using all the solutions listed above but the "UE4 fatal error" always appears

One point is that when I launch the game directly by clicking directly on the Medieval_Dynasty.exe file (located at \SteamLibrary\steamapps\common\Medieval Dynasty)
or Medieval_Dynasty-Win64-Shipping.exe (located at \SteamLibrary\steamapps\common\Medieval Dynasty\Medieval_Dynasty\Binaries\Win64) the game launch propoerly and I could play without any problem
My point of view is that since the update something is missing with the shortcut used by steam to launch the game (file path, ... )

Nevertheless clicking directly on the .exe file works for me everytime.

If you have the problem with two games, something might have changed in your pc? MD and Sengoku have been made by two different dev studios, independent of each other. The only thing they have in common is that they are both using the Unreal engine, albeit a different version (Sengoku is on 5, while MD is on 4).

Can you try launching the game with dx11, just to make sure? in your Steam library, right click on Medieval Dynasty in the list, go to "Properties" and in 'general' under the "Launch Options" window add: -dx11

If that doesn't work; could you provide a dxdiag report so the more technical people can have a look? https://support.microsoft.com/en-us/windows/open-and-run-dxdiag-exe-dad7792c-2ad5-f6cd-5a37-bf92228dfd85
To upload it, just use a site like wetransfer.com to create a link for you that you can paste here (no need to make an account on wetransfer, just click the 'i just want to send files' link.)

Same for you. Could you try by launching as -dx11 and provide us a dxdiag report after you made sure you update the drivers of your graphics card?

TLDR; Reinstalled Epic Games Launcher and it works now.

As it happens, my Epic Games Launcher had become corrupt and wouldn't update (per the first suggestion to update Unreal Engine by SwordsOfTheSouth). So after a brief reinstall of Epic Games Launcher, it's all running peachy again!

Apologies for my fallacious assumption that toplitz's packaging had something to do with it -- it was all Unreal-powered games that were failing, I realized after some more testing.

Anyway, thanks for the responses and support!

I have the same issue, without epic games launcher installed

Please let us know if you tried all the steps described in this post (and the links), so we don't have to repeat the same thing over and over again. :-) This issue can have different causes.

Thanks for letting us know, since this might help someone else as well! This error can have so many different causes that it's very difficult sometimes to figure out what exactly is wrong.
