Unity 2019.4 Android/iOS Native crash that happen to most users at some point

Hi there,

I have updated my project to 2019.4 LTS and tried the build with a group of closed alpha testers.

1. Some users in my game reported that they were unable to enter in my game.

2. After some digging and implementing firebase crashylitics to receive insights about what is happening, I discovered that is related to the save system. I encode the user data and store it in the player prefs.

2. I implemented custom crash reports with try-catch to see what is happening and the problem is that the json that I load from PlayerPrefs is

JsonEncrypted ��
Crashed decoding the json EncodedJSON:��

3 Users first experience a crash, and then after loading the app again they problem appears. It appears to be random crash since users have experienced it on different stages of the game (Maybe, its related to write in the player prefs, but this is just a thought)

4. After a lot of trying to reproduce the problem on my device, I have finally reproduced it (I tried more times but only happen once and it was just after leaving the app and open it again), and the problem appears just after a native crash that I attach here

Any more is having such crashes?

 

Thank you for the reply, I have recollected more info.

The ram doesn't seem to be the issue since all of the affected devices have at least 500mb of free ram.

The OS having this issue is Android 8,9,10 but I have 1 user reporting the same error on iOs (I can imagine that the issue is related since it reported the same problem, crash and then infinite loading, I can't confirm since I didn't receive the crash)

The issue has been reproduced in (after implementing the firebase crashylitics, so more devices have experienced it) Xiami red mi note 6, red mi note 9 T pro, Huawei P10,Galaxy S20 Ultra 5G, moto g(6) play and CUBOT King kong 3.

Let me know if you need more information.

There is the full stack trace of the device where I was able to reproduce the crash.

Thank you for taking the time to answer the question.

The only thing I can think of using the UI thread is Google play services ( Since this is related to the save system, I can guess that the app get killed while using google play cloud saving feature?). Other than that, there is nothing that uses the UI thread.

The only lengthy operation that can be there is the save system saving the game online to the google play services cloud.

Shouldn't be this handled by google correctly?

Regarding the stack traces, I have the symbols ( I am using IL2CPP) for this app version. If I use the symbols on the error I can retrieve the stack trace right?

This should be converted to stack trace

Code (CSharp):

1. Cause: null pointer dereference
