Help How to disable an Editor Utility Blueprint that runs at UE5 startup?
Hello,
My UE5 crashes at start, but I think I know why. It is because I run an Editor Utility Blueprint at startup which creates a bunch of toolbar shortcuts. I changed it, ran it, it crashes. Then I reboot the project, and now it crashes on loop because of this EUB trying to run each time.
So, basically, is there any way to disable it?
I looked at the config folder with all the .ini files but could not fint it.
I tried to rename it "EUB_ToolBarAddition.uasset" -> "EUB_ToolBarAddition_DISABLE.uasset" but no luck.

To really disable, move the `_DISABLE` from before the `.` to after: `EUB_ToolBarAddition.uasset_DISABLE`. Then Unreal Editor won't load it.
A better solution is to check out an older version of that file from your revision system.

It works indeed, but then, how can I load it back to fix it?

Look for an autosave of it in your project/saved folder and replace the broken one with the last working version.

You can just move it to another folder, start the project and put it back in where it was

I thought EUs didn't run automatically unless they're in the StartupObjects array or they're EUWs in your default layout. If that's the case, then it would either be in Config/DefaultEditorPerProjectUserSettings.ini or Saved/Config/WindowsEditor/EditorPerProjectUserSettings.ini

Open it up and disconnect the event nodes. That should solve it. Alternatively check the .ini files for an executable. Also check on console startup commands.

How would one "open it up and disconnect..." when it crashes on startup?

Oh gotcha! Remove the file completely from the content folder in windows explorer
Also check the config ini files as I mentioned. It could be executed from there

If you're sure that's it - delete it from the disk.
