    So now 2021.3.36 is out but this is still a known issue according to the LTS releases web page, even though it says here that the fix is in review for that very release. Great procedure, Unity

    There is a workaround to reduce the probability of the crash: https://forum.unity.com/threads/google-console-libil2cpp-so-sigbus-crash.1485249/#post-9544891

    We're going to be stuck on 2022 for a while. Will need a backport

    This really needs to be back ported to at least 2022 as it is causing a lot of issues.

    Using mono as scripting backend is not possible, as Google Play Store only accepts ARM64 builds, and that requires IL2CPP. So we are stuck with an undiscoverable app until this issue is fixed
