ARFoundation crashing on start app

Hey,
I was working on ARFoundation 3.0 project for a week but since yesterday the app started crashing on start. I could not figure it out so I built out a the TogglePlaneDetection example and that crashed too!
I don't know what's going on..
Here's the console output from Xcode on the TogglePlaneDection project.

34. Message from debugger: Terminated due to memory issue

 

I restarted my iPad and the planeDetection example is working. Looks like my previous app was holding on to the memory or something.

 

After running my a little while, I always see this message. JobTempAlloc sounds serious but I wouldn't know how to correct this behavior.

Code (CSharp):

1.  
2. Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak
3. (Filename: ./Runtime/Allocator/ThreadsafeLinearAllocator.cpp Line: 539)
4.  
5. To Debug, enable the define: TLA_DEBUG_STACK_LEAK in ThreadsafeLinearAllocator.cpp. This will output the callstacks of the leaked allocations
6. (Filename: ./Runtime/Allocator/ThreadsafeLinearAllocator.cpp Line: 541)
7.  
8. Internal: deleting an allocation that is older than its permitted lifetime of 4 frames (age = 5)
9. (Filename: ./Runtime/Allocator/ThreadsafeLinearAllocator.cpp Line: 313)

I found out the memory issue. Once I place in gameObjects in the scene, I had to turn off plane detection or it'll lead to the memory issues.

 

Oh, I also had Image tracking on too. It looks like image tracking uses Job too.

 

Updating to 2019.3 fix this memory leak issue. I heard it was to do with something called ShaderCompiler.
