Hi,

You need to use symbols to resolve the stack trace. Here is the documentation about how to generate them:

After the symbols are generated, you can use Android Logcat package to resolve the stack trace. (The symbols and the player must match)

The latest version of Unity 2021 is 2021.3.38f1. You are missing 27 versions of patches.
Maybe just updating your project to this version will fix your bug.

That’s indeed what I’m hoping for. The game is already live so I want to get some hard evidence first, especially since the crash is very hard to reproduce.

Hi! I have a similar problem. Have you managed to resolve it?

Thank you @Alan-Liu for the tip. I ultimately needed the step by step guide for the Stack Trace Utility which would have been very hard to find.

I updated to the latest 2021 LTS and am still getting a rare crash. My stacktrace points to a problem in DynamicHeapAllocator, which makes sense but I’m not 100% sure if my symbols match the player. My plan is to push an update and keep an eye on crash reports now with a reliable backup of the Android symbols.

@Imm0rt4l_PL I recommend resolving your stacktrace to find out more. It might reveal a bug that you can fix or it might point to a bug in the engine, which for me is currently a dead end.
