Crash when quitting unreal engine

When I quit the engine via command Q or through the menu, I get this error. Note that this is not when closing a map in the editor. I’ve restarted the engine with no change. This happens only after opening a specific project.

This error looks different than others - is it referencing a problem with widgets?

Hello Skifree,

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. If not, could you provide the project that is having this issue?
  4. Have you tried using the drop down on the launcher to verify your engine version?
  5. Have you tried deleted your save and intermediate files?

I cannot reproduce this in a clear project, and it has seemingly stopped happening for the moment. If it starts back up I will post something.

Hello Skifree,

I am happy to hear that the issue is no longer occurring. I will be converting your last comment to an answer for tracking purposes. If at any point the issue returns, please feel free to reopen this issue with any additional information you may have by posting a reply.

Make it a great day
