Hello folks, weird bug, this morning i succeded to build in shipement my project, but when i tried to build in Development i encounter this weird error (i will paste it below). I’m on the 5.5.4 source build because i need to deploy server on Linux for information, but here i try to build for Windows in Development, here’s the log :

Hello there @Algost!

Checking through your extended log, there seems to be a conflict between the shaders you are cooking, and your current cache. The main assertion error you are getting, “ShaderCodeResource.GetFrequency() == Frequency”, refers to a mismatch in shader frequency metadata. This is most likely due a corrupted or stale Derived Data Cache.

As for the reason behind this, it’s likely due the build change. When you completed the shipping build, UE generated a set of shaders. Then, you switched to development, and the engine tried to re-use those assets, but this type of build didn’t read said cached shaders properly, leading to the frequency mismatch.

So, in order to solve this problem, a full cache clear and shader rebuild is in order. To do so, please close UE, navigate to your project’s main directory, then delete folders Intermediate, Saved, and DerivedDataCache. Also, go your local app data, and delete the DDC from there as well (usually at %LOCALAPPDATA%\UnrealEngine\Common\DerivedDataCache).

After those changes, restart the project, and all shaders should recompile. Test building again, if the issue remains, you can manually force a new recompile from engine, by opening the console and entering “recompileshaders all”. Once completed, test the build once more.

Hey Brs-sebascova, thank you for your answer. I try your first method which is :

  • Delete DDC, Intermediate and Saved from my repo + from %appdata%/local/UE/Common/DDC and when i reopen my project it reopen instant so i was thinking it doesn’t do what it’s suppose to do. i try to rebuild and i’ve got the same error, but i was expected it

  • After that i try the line in the terminal “Recompileshaders all” and i let my pc rebuild, but i had a error message saying that my unreal crash on ShaderCore.h line 1362, i leave you the picture in attachment.

    How can i fix my unreal engine ? I always have weird problem with this engine, it’s so unstable for me x))

Hello again!

Thank you for your follow up, the direct crash error you are getting is still the same one as the log. This means, that the shader mismatch remains active, even after clearing up DDC. So, we need to make sure that no traces of said cache are left.

You already deleted DDC from the project and from local app data. There are two more possible locations, if they were created by engine:

%LOCALAPPDATA%\UnrealEngine\ShaderCache
C:\ProgramData\Epic\UnrealEngine\Common\DerivedDataCache

Please check if that folder exists, and also delete …Common\DerivedDataCache again from local. After that, from your project’s directory, go to Config/DefaultEngine.ini and edit it, adding the following line:

[/Script/Engine.RendererSettings]
r.ShaderPipelineCache.Enabled=0

This will avoid loading any cached pipeline, thus preventing the frequency crash. Now, open the project, and allow it to rebuild shaders again, it should create a fully, new cache. After that, you can remove the pipeline change line.

Now, if the issue remains even after these changes, then the remaining path is a full uninstall/reinstall of all Epic software from your setup:

  • First, uninstall the engine, launcher, any asset packs, etc
  • Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
  • Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
  • After that, no elements related to UE should be left in your system
  • Now, reinstall UE launcher from scratch, and only add the version of the engine you were using for your project (in this case, UE 5.5.4)
  • After the process is complete, test re-opening your project
