Unity Editor Crash During Build (Temp Folder Issue?)

I’ve been having an issue recently regarding the editor crashing with a particular project. The project folder is 20GB, so I can’t really attach it to a crash report, however I’ve narrowed down the issue due to the unique circumstances of the crash.

Here is the case number for the crash: Case 889729

I can reproduce the crash 100% in Unity 5.5.1p4 and 5.5.2f1, but building works fine in Unity 5.5.1p3.
Because of that, I can compare editor logs, and it seems to have to do with opening the Temp folder scene.

Here’s the Editor log for the successful build

...
Packing sprites:
- Grouping sprites using the selected SpritePackerPolicy.
- Packing 0 atlases.
- Packing completed.
Opening scene 'Temp/__Backupscenes/0.backup'
Load scene 'Temp/__Backupscenes/0.backup' time: 0.015584 ms
Unloading 4153 Unused Serialized files (Serialized files now loaded: 0)
System memory in use before: 455.5 MB.
System memory in use after: 455.1 MB.

And here is the log for the crash

...
Packing sprites:
- Grouping sprites using the selected SpritePackerPolicy.
- Packing 0 atlases.
- Packing completed.
Crash!!!

I was able to build a separate project with the same general setting perfectly fine in 5.5.2f1, and the crash always happens in the same exact spot, so I assume there is something specific to my project.

Any help would be appreciated :slight_smile:

Bump - Still can’t figure out the issue

  • Running unity in Admin mode did not affect outcome
  • Deleting Library and leftover temp folder (doesn’t get cleaned up after crash) did not affect outcome

Bump again? - Still crashing, haven’t heard anything back on the crash report either.

Please let me know if there is additional info I can give

Hi, i’ve got the same issue and still can’t figure out how to fix it, have you solved it?
