Server build shows a "corrupted files" error

Hello. I’m running into somewhat of an odd error trying to create a server build. I think it’s probably something really simple on my configuration, but so far I’ve had no luck in pinpointing what it is.

Basically, I’m trying to build a very simple server build. I’m using the default 3rd person template, following this tutorial.

Everything goes smoothly up until I run the server build, in which case, I get the following error:
[2022.05.06-14.28.13:968][ 0]Message dialog closed, result: Ok, title: Serialization Error : Action Needed, text: Corrupt data found, please verify your installation. Assertion failed: CurrentPos + Count <= TotalSizeOrMaxInt64IfNotReady() [File:C:\UnrealEngine\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading.cpp] [Line: 7791] Seeked past end of file /Engine/EngineResources/WhiteSquareTexture (129645 / 3851)

I’ve checked this thread, which solved the error by erasing the UnrealEngine folder in AppData, but no success there. Client build works fine. Hell, I can open it as usual on the editor and nothing’s wrong.

I’m sure the error is really simple, and it happens with either 4.27 or 5.0, so I have a hard time believing it’s a bug on 5.0. Any clues?

EDIT: On Visual Studio, I see a “corrupted files, verify your installation:” dialogue before the error message on the build shows up on the terminal.

Ran into the same issue. Skip that step (2.10) and continue on through the rest of the guide and it should work fine. FYI they say “Package Project” is under the file menu, but I could only locate it by clicking the “Platforms” dropdown and selecting a platform. Also, I had an issue where I could join the server in editor but not in the built client, re-compiling and saving my level blueprint fixed it.

Hi, Running into the same issue with a project of mine. Did you manage to solve this?

You should cook content data from Editor Menu: Platforms/Windows/Cook Content
with making menu item ‘{projectName}Server’ checked.
