    This is the error stack。。

    It work well at 2019LTS。

    Edit:This error happens on mono, and il2cpp works.

    I had the same issue while building for Android (Oculus). Changing to IL2CPP fixed for me too

    I don't think you can fix it from your side, unfortunately. The problem had to do with how the machine.config file from Mono was used in the Unity build process internally.

    So it might be the case that this still happens on Linux, even though we corrected it for Android. Can you submit a new bug report?
