We’re looking in to a shader-related crash which is occurring for some players after the Expeditions update.
The error produced in the crash reporter when this occurs will look similar to:
[Engine Error]: HRESULT: 0x80070057 = E_INVALIDARG, assert: shader ‘#ID[8860321b]’`
Once we have updates to share, we’ll let you know in the comments below and link the posts here.

Sorry to see this. Firstly, do you have any parameters set in Darktide’s ‘Launch Options’ as outlined here?:
hello, sorry for jumping in convo, but i have the exact same crash ( crash link –> crashify://2eba7cec-bc1d-4b0e-b16e-abb35bfb3b77 ), so i checked parameters in steam, and its empty, so problem seems to be not there…
i didnt have any side mods for this game, tried to verify file integrity twice, didnt help

Have you tried rebuilding shaders? Error message looks like shaders related.
According to AI:
To rebuild shaders in Darktide and fix stuttering or crashing, you must delete the shader cache files located in your AppData folder. Type %appdata% into the Windows search bar, navigate to Roaming\Fatshark\Darktide, and delete the shader_cache and compiled_shaders folders. Restarting the game will force a fresh rebuild.
Steps to Rebuild Darktide Shaders
Close the Game: Ensure Darktide is not running.
Locate Cache Files: Press Windows Key + R, type %appdata%, and hit Enter.
Navigate: Go to AppData\Roaming\Fatshark\Darktide.
Delete Folders: Delete the shader_cache and compiled_shaders folders.
Restart Game: Launch Darktide, and it will re-compile the shaders during the loading screen
Could you please correct the article:
@gideon404 confirmed that the maximum value of the parameter is 2048. I confirm that the game launches and runs correctly with this parameter set to 2048. Most problems with launching the game occur when the parameter is set to a higher value.
Nah, didnt help
No
Thanks for checking - I’ve escalated this with the team.

hello, while following steps, i checked 4th one in these folders, and from “ shader_cache and compiled_shaders folders “ i have only shader_cache.hans one, so the second one in some other folder? Sorry, im very far away in my knowledge from correcting this kind of errors
Seems like it has changed overtime. Let me ask AI or google it for you 
Will edit this post soon.
To clear shader cache created by Darktide, you can remove following files in %appdata%\Fatshark\Darktide:
shader_cache.hans
shader_library.pso_lib
state_stream_library.pso_lib
After starting the game, the files should be recreated.
Hey loonechkaa, which GPU model do you have? I only see AMD Radeon(TM) Graphics, with no model number, which would conventionally be an integrated GPU.
AMD Ryzen 5 5600U with Radeon Graphics by AuthenticAMD, i have this one only, and before update it was enough to play on a low graphics w/o any crashes
Hmmm, I am surprised it worked without issue before admittedly! Could you try this?:
If Steam Cloud saving is enabled for Darktide, this may automatically restore the AppData and consequently cause the issue to resurface.
NOTE: By deleting your AppData, operative loadouts and custom keybindings will be reset. You may wish to make a back-up of the directory in the event deleting your AppData does not work to resolve the issue.
AppData\Roaming\FatsharkYou will then need to use the ‘Verify Integrity of Game Files’ option, which is accessible via the Steam client and will ensure the installation is complete.
i deleted them from folder and launched game again, nothing changed at all… same crash, same error code and etc…
Decided to consolidate these reports so it’s easier to keep you updated (I know I told you to share your post separately loonechkaa, my apologies!). Anyway, our Engine Developers are looking in to this - I’ll keep you posted.
Same here. I’ve even tried reinstalling everything but nothing helped.
So … no new game mode for me
Great (as always).
