"Plugin 'X' failed to load because module 'X' could not be found.

After some downtime, I pulled an old project and tried to run it on an iOS device, but I receive the message below.

Plugin ‘datasmithcontent’ failed to load because module ‘DatasmithContent’ could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.

I do not have and am not using Datasmith. I have no extra plugins installed for the project or for the engine.

When I run the project on macOS, it runs just fine.
I have tried deleting the engine and redownloading (I’m using the pre-built engine from the launcher), but I get the same message.

Try finding the plugin in this folder under your game dir. (check children folders of Plugins too)

Otherwise, does the engine load up or gives the error at the attempt?

Deleting the Intermediates, Saved, and Build directories resolved this issue for me.

Thanks for the help, Arty, but I don’t have that folder. I have not added any non-default plugins to this project.

i know the reason,have you ever use this old project in 4.19?if that,you should delete the app on your phone and then reload it

ylmoro was right, that fixed it for me. Cheers buddy, thought I was on the verge of losing my project and backup to a non-existent plugin problem!

If it is a prebuild version of unreal what you can do is copy the “BuildId” tag from another plugin within /Binaries/Win64/UE4Editor.modules into the same file of the “X” module.

For Eg:
“BuilId” tag in

Engine\Plugins\Animation\LiveLink\Binaries\Win64\UE4Editor.module to X\Binaries\Win64\UE4Editor.module

This error occurred for me when I had tried to copy the latest plugin folder to the old plugin directory, and overwrite all duplicate files. There were some errors at the time, about certain files being locked, which I ignored. The fix was to completely delete that plugin’s folder and replace with the new 4.25 version of the plugin (a plugin which is not on the marketplace, therefore must be manually-integrated to the project).
