Unity 5.2.0f2: Editor sometimes freezes when leaving play mode

The editor sometimes freezes when leaving play mode (Windows 7). The only option to continue is to kill the Unity.exe process and restart the editor.

Anyone else having this problem?

PS: The editor freezes, does not crash as reported here.

 

Please grab a crash dump via Task Manager and submit a bug and report the # here.

 

I'm not able to reproduce the freeze anymore. Now it also crashes every time I leave play mode, bug reported as:

(Case 723283) 5.2: Editor crash when leaving play mode

I guess it's a duplicate of this one, but who knows.

 

Today the editor is freezing again when leaving playmode. Submitted the following bug-report, dump attached as well.

I don't have this issue, but I had a similar issue 1 or 2 years ago. Just a long shot; I'm thinking of things that are started on scene playback and stopped when leaving play mode.

So, maybe

• adb.exe? http://forum.unity3d.com/threads/bu...when-entering-play-mode-in-the-editor.148176/
• native plugins? http://issuetracker.unity3d.com/iss...playback-with-native-plugin-which-calls-win32
• unityVS?

 

A quick look at the bug seems to be something related to logging regarding recalculating the hierarchy view. Having folk take a look.

 

I had the same problem and I solved it by disabling "Preferences / General / Enable Alpha Numeric Sorting". I think something is wrong with "Alphabetical Sort".

This is the loop that cause the freeze.

 

No, I haven't noticed the issue in an empty project, but I didn't spent hours trying to reproduce it there.

I don't do anything special to trigger the bug. I just press Play, play the game for a few seconds or minutes and press Stop.

I can repro the bug with my project rather easily, but also not always. It requires a few tries:
* Start Unity
* Load Scene in editor
* Press Play
* Play 3 minutes
* Press Stop
=> Editor freezing or crashing.

The game is loading and creating game objects while it's running. I might had have "Alphabetical Sort" activated, but I'm not certain because I switch between Alphabetical and Transform-Sort back and forth as needed. I often use the "Mute Audio" option in the editor. I usually have VS 2012 open the entire time.

Hi Shawn,

Wondering if this could be related to a similar crash bug I reported? Case number 720757.

Thanks.

 

100% repro here. Submitted bug report. Will try disabling alpha sort to see if that fixes it.

 

disabling alpha sort seems to have fixed the issue.

 

disabling alphabetic sorting fixed the issue for me too.

 

Not sure the status of this at this point but this was also happening to me and after reading the posts here, was remedied by disabling alphanumeric sorting.

 

Just ran into this issue.

No bug # yet.
It was caused by calling "DontDestroyOnLoad".

 

I'm having Unity Editor 5.2.0f3 crash or freeze completely white every time after exiting play mode. Alphanumeric sorting disabled. Development environment is Mac / OS-X.
