Question Any help to hunt down a cloud build crashing on iOS

Hi there community!

I'm struggling to get a running build out of the unity cloud...and i'm out of ideas. I would graeatly appreciate if somebody could guide me in some direction:

Unity ver: 2020.3.21 (locally), 2020.3.20 (cloud)
Xcode ver: 12.4.0
via GitHub

Building the project locally, it's running just fine.
Building in the cloud finishes successfully but crashes after the splash screen afte being deployed on several test devices via appcenter.

I tried to symbolicate the crash log, using the described way in the forum and on the support pages but without luck.
The crash log begins like this:

Code (csharp):

1.  
2. Exception Type:  EXC_BREAKPOINT (SIGTRAP)
3. Exception Codes: 0x0000000000000001, 0x000000010601c220

6. Thread 0 name:  Dispatch queue: com.apple.main-thread
7. Thread 0 Crashed:

11.  

Diagnostics aren't showing any crashes.

As i said - i don't know enough for further investigations so i'm thankful for every comment.

Thanks,
grIIIe

 

I managed to get the symbolized logs but now i have a hard time to interpret them. Maybe now somebody can give me a hint?

Have you tried a development build or is that what you're already running? I'd also not recommend doing a cloud build on an older version of Unity than your project is on. Although the minor editor increments don't change much you could have assets that have been saved in the more recent version and that could cause some kind of parsing failure on the older version of Unity that you're using on the cloud build.

To rule out any issues with your own code I would create a new startup scene with a simple camera (with a coloured background) and make that the only scene that's in the build settings. If that doesn't work then at least you know it's not related to your code or other assets.
