    I'm fed up with this issue. Still, it happens in 2021.2.7f1. What is the Unity version should I try to build for Android without this issue? I have a Mac M1.

    As of 28 March 2022, this bug seems to occur on Unity 2019.4.35f1,2019.4.36f1,2019.4.37f1.
    Downgraded the project to 2019.4.34f1.

    The build is working fine on this version for me.
    "IL2CPP: Fixed incorrect exception filter handler on try blocks with multiple catch blocks. (1335434)"
    this fix might cause the issues.

    On the release notes 2020.3.27f1 is lists this bug as a know issue -

    ...but on this page it says this bug was not reproducible with 2020.3.27f1 ?
