An Unreal process has crashed

[Doctor Flames]

I am getting this error always after I beat the first boss and some times when I launch the game. I reinstalled the game, the nvidia drivers, verified the files etc

LowLevelFatalError [File:C:\Unreal_TC\Engine\Source\Runtime\RenderCore\Private\ShaderCodeArchive.cpp] [Line: 354] ShaderCodeArchive::DecompressShader(): Could not decompress shader (GetShaderCompressionFormat=Oodle)

Specs rtx 4090 and 13700k, 32gb ram and 2 tb m.2

I keep my fingers crossed someone knows how to solve this

Is your GPU overclocked either by you or the manufacturer? I actually had to underclock my previous GPU, a 1060, because of errors like this with unreal engine games. I don't know if that is your problem, but it is worth a shot.

I'm also getting it both at startup and if I get further basically every area load. Also 4090 FE. I've done all the usual things, and even the Unreal specific windows tweaks HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\
TdrDelay = 60
TdrDdiDelay = 60
Basically the same error was happening on Deathloop for me until they patched it...
Even though this is Unreal 4.x Epic has a guide about this in the 5.x docs

"GetShaderCompressionFormat=Oodle"

So basically the game is trying to decompress textures using PS5 Oodle decompression tech, which has a dedicated hardware accelerator chip by the way.

>Game designed to work hand in hand with PS5 decompression with I/O accelerator tech. >Said tech does not exist on PC.
>Release game on PC anyway, but change nothing about asset streaming and just hope it all works well with upscaling.

Guess we're waiting for an update to asset streaming....

Win 8 compatibility mode + the registry change fixed it for me. I hope this helps others!

Try clearing shader cache and verify install.

I believe like all people who had/have similar problem I tried every possible solution, changing BIOS settings, reinstalling windows, bla bla bla, everything. Was about to give up and just wait for the patch but I remembered I had similar problem long time ago and reinstalling graphic drivers for old one did the trick. I have GeForce 3060 and did install the December 2021 drivers. Game is stable for over 2h. Of course I don't believe this is the solution and it's very possible the game will crash, but for me it works for now.

Validate game files and then run in windows 8 compatibility mode as admin.

Disabling my 13700k e cores fixed everything for me after hours of constant crashes.

I checked the game folder and for sure my guess was right.
It's using a unpacker to unpack PAK files when you boot up the game, this means it's CPU and RAM and VRAM intensive to unpack all the game files to start the game.

That's a developer oversight issue, they somehow called that directory in the game code instead of utilizing local files.

[File:C:\Unreal_TC\Engine\Source\Runtime\RenderCore\Private\ShaderCodeArchive.cpp]
File Directory

[Line: 354] ShaderCodeArchive::DecompressShader(): Could not decompress shader
It couldn't decompress the file indicated because it doesn't exist.

(GetShaderCompressionFormat=Oodle)
It's using Oodle's file decompression algorithm which is super fast and efficient, but needs to be implemented properly.

I have the same problem. I cannot start the game. It carshes every tiem. 4090, i13900k

There are work arounds. Launch as admin in windows 8 compatibility mode. Works for most people.

I'm doing exactly that. 3070, 9900K. Lowest graphics settings. Still crashing consistently between 0 and 5 minutes into launch. Maybe once every ten tries I can get about 10-15 minutes of play. ._.

I noticed it stopped happening when I set everything to ultra and stopped messing with settings so IDK.
