Question The game crashes on release builds. On development builds - no

My app has native crashes. In the process of investigating this issue, I noticed one exciting point.
When making a development build I can not catch crashes at all.
For example, during gameplay, I have random crashes. Usually, they can appear after 5-10-20 min of gameplay.
But if I make a build with the same code, but with a development build enabled I can not catch crashes. I played from 1 to 3 hours on different devices, and not seeing crashes. Hard to believe this is a coincidence, especially after reading similar tread https://forum.unity.com/threads/my-...n-release-build-but-not-on-dev-build.1040170/

My question is, does anybody can tell me why this behavior happens? What difference between development and release build builds? Maybe I can change something in settings to get the same result but on the release build.
Or probably give me advice on which direction I have to investigate to solve my crashes. Just in case, additional information is below.

Unity version :
2023.1.0b12.3067.3607

Any suggestions? Each day I'm receiving those crashes and I wish to solve it asap.

 

Thank you for your answer. So as I can see there is no way to understand why I cannot see crashes in development mode.

I do not understand how to use this StacktraceUiility. Can you please little bit explain about StacktraceUiility?
Is this the correct workflow with StacktraceUtility? :
1. Create a build.
2. In Android Logcat settings add a path to created .symbols (I have enabled Strip Engine Code)
3. Keep playing until a crash appears
4. Copy the crash log from Android Logcat and paste it into Stacktrace Utility
5. Press Resolve Stacktrace to see additional information

I've been trying to catch crashes, but for now, I can not catch them on my device, need more time. If this is the correct way of using the utility, ill continue playing until crashes.

Also, I tried to add a path of my release .symbols (production version) into Android Logcat settings and Copy the crash log from Firebase (e.g Crashed: Thread: SIGSEGV 0x000000000000004b ) and paste it into Stacktrace Utility. But in this way, I didn't reach any success, probably this is not the correct way of Using Stacktrace Utility

 

Thank you for clarifying. Unfortunately, when im getting a crash, the error message doesn't appear in the Android log cat. So in my case, Stacktrace Utility doesn't help.

 

In Android Logcat crash errors did not appear, at least I didn't find them.
But I have good news, after moving a project to a new unity version 2023.1.0f1, the first and second errors from the first post are gone. A third crash sometimes still appears, but I noticed it happens only when the game is reloading, and it happens pretty rarely, so this is no longer a big problem for me.

 

@stream_in_space_ do you fixed error 3: tlsf_remove_pool?

 

I changed the Unity version, and I'm not getting this error exactly. However, according to Crashlytics during the past 90 days, I still have similar errors.
Example :
1

null pointer dereference: SIGSEGV  0x0000000000000018

Honestly, I don't think that we can somehow fix those errors. It seems they are related to the Unity version and it is a bug on their side. Probably those errors will gone with the new Unity versions
