Crash when saving scene, and loading scene.

When saving the scene in Unity 2017.2.0b2, Unity hangs for 15 seconds, then crashes.
The same happens when I created a new scene and opened it.

I think the crash when the scene saves is happening because I have a custom editor script that converts scenes to a prefab when it saves, but I don't know why it crashes when loading a scene.

If you need the log files tell me.

 

I recommend to submit a bug-report following the advice in this document. Using the bug-reporter seems to be an important step, because that makes sure the report is in their bug-tracking pipeline and has to be processed at some point. Using the forum is often used to add to an already submitted bug-report a little more attention.

It's advantageous to attach a project to the bug-report that Unity can use to reproduce the issue and test their fix against. The easier an issue can be reproduced by QA, the more likely it is to get forwarded to a developer, who might or might not work on a bug-fix for that at some point.

After you submitted the bug-report, you receive a confirmation email with a Case number. Unity often asks us to post the Case number in the forum thread, which allows them to find that bug-report if they look at your post.

Following these steps will increase the chance that Unity is looking at your issue tremendously.

 

Thanks for the Help!
