Hello,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Is it possible for you to open up the blueprint in another project so as to correct what it is that is causing the crash?
  4. Can you open the blueprint up in an older version of the project that can be found in the back up files that are automatically generated?
  5. If so, could you provide screen shots of the blueprint?
  1. Yes
  2. Paste attached blueprint(Minion.uasset) to ‘Content\Blueprints’ folder or anywhere inside the project I believe → double-click to open ‘Minion.uasset’ Blueprint file in editor
  3. It is not possible, crash occurs always when I double-click ‘Minion.uasset’ blueprint file in order to open blueprint editor.
  4. I tried, file does not open.
  5. Screenshot from blank project provided.

Hello,

I was unclear before when I asked if you could reproduce this in a clean project. What I meant to ask was if you could reproduce this issue in a clean project with no existing assets from the project that is having the issue. As for your back up files not opening, do you mean that nothing happens when trying to open the project or perhaps that it crashes when trying to open one of your backup files?

The Default path can be found here:

C:\Users\YourUserName\Documents\Unreal Projects\YourProjectName\Saved\Backup
