[4.10.0] UMG - Set Key Time crashes engine

Clicking on the Set Key Time option when right-clicking a key in a UMG animation will crash the engine. I have reproduced this in a blank project.

  1. Create a new blank project

  2. Create a widget BP

  3. In the Widget, create a new animation

  4. Add any component to your widget so you can have a key on the timeline

  5. Add a key for your component in your animation (like position or whatever, anything works)

  6. Right-click the key and select Set Key Time

This happens 100% of the time.

Hello ,

I was able to reproduce this issue on our end. I have written up a report (UE-23845) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day
