I’m using engine version 4.10.2 I just imported a .obj file and the editor was not responding. So I closed it using “task manager” and restarted the editor. Then it is constantly crashing. Here’s the crash report.

Hello -

I believe that this crash may have been resolved in 4.11, however I cannot find your crash report in our system. Can you recreate the crash again and make sure to submit the crash report to our system and let me know.

Thank You

Hello -

First Thank you, I have found the crash report entered. Unfortunately it is not the same crash that we have already identified.

To get you back in the engine and hopefully your project, go to teh project directory and see if in the content directory there is a *.uasset for the imported OBJ. If so, delete the uasset file and let me know if the engine opens without crashing (you will get some errors in the project most likely).

Also, if you can upload a copy of the OBJ here (simply place it in a zip file and attach), that will help us narrow down the cause -

Thank You
