Hey there @WarrotAryan241! It looks like it’s failing to load a plugin attached to your project.

This is a default plugin to help show asset data, so it’s odd that it’s module isn’t there. Back up your project first, then go disable this plugin, restart the editor, then reenable the plugin and restart the editor, then try another debug build. Let me know how that goes!

Hello there,

I am having basically the same issue but with a different plugin. For me it’s “GameplayTagsEditor”.

Also, funny enough, this only is a problem after I’ve changed directories.

First, my project was in Directory A, there when I package it all works fine. There, I’ve zipped up the project from File > zip project and then unzipped it in the same parent directory. Everything worked again.

Now, if I take the zipped file and unzip it in a different directory than the original one, it does still package fine but I can’t open up the .exe and instead am confronted with this Error message.

LogPluginManager: Error: Unable to load plugin 'GameplayTagsEditor'. Aborting.

Packaging gives no warnings or errors in either directory. It does all work if I add a c++ class so that the project becomes a c++ project but that’s not an option for me as the project is intended to be a bp template. Also, the versions tested are 5.3, 5.4 and 5.5. Initially, I’ve started the project in 5.2 but due to some missing features I had to upgrade to 5.3 . Because that lead to many broken bp’s, I’ve created a blank 5.3 and migrated each asset individually to find the ones that couldn’t handle a version upgrade. Why am I saying this, well, the 5.2 one does work in other directories too.

If you have any idea what the issue could be, I would appreciate any help.

This might be a stupid question, but I had something similar when switching UE version.
Have you placed the plugin in the new UE version too?

Or if you already have done that, are you sure the plugin is compatible with the new engine version?

That’s a default unreal engine plugin which makes it even more strange. The Gameplay Tags Editor allows you to use Gameplay Tags. I don’t even have a plugins folder added to the project

That is indeed very strange

OGMainMenu.log (5.1 KB)
Here are the logs.

The following line also gets printed with working builds too so I don’t think it’s the problem here.

LogStreaming: Warning: Failed to read file 'C:/GameDev/UE/Templates/MainMenu/OGMainMenu_5.3/Build/Windows/Cloud/IoStoreOnDemand.ini' error.

Alright so… I found the issue and I really cannot comprehend how stupid this is.

Due to it being a project intended to become a template, I placed it into a folder called “Templates”. Now, that’s the problem. Unreal Engine utilizes that folder name itself for the Eninge Template projects and that’s why it thought my project was a template too!

“What’s the problem, your project is to become a template, right?”

Yes, but not a template in the Unreal way but instead a marketplace template because internally Templates have other plugin presets and thus it aren’t supposed to work like “normal” projects.

So yea, for anyone seeing this, don’t ever name the parent root folder of your projects “Templates”. Just don’t, it doesn’t mention that in the logs or anywhere. I randomly figured this out by unzipping in testing in other folders too and narrowed it down to the templates one. Then I googled it and found out Unreal treats these ones differently.

Anyways, enough hair loss for a day.

wow good catch, but that’s just really weird.
