    This ( or something extremely similar ) still happens in 2019.4 LTS.
    Did not repro. in a separate project though.

    This crash is still occurring in Unity 2019.4 LTS and Unity 2020.1 Beta. The issue can be reproduced by having a realtime light source with shadows enabled and a UI canvas in the same scene.

    IsNodeVisibleFast(SceneNode const&, CullingParameters const&, LODDataArray const*)
    void ProcessShadowCasterNodeVisibilityAndCullWithoutUmbra_Kernel<(CullingParameters::LayerCull)0, 8>(IndexList&, CullingParameters const&, LODDataArray const*, SceneNode const*, AABB const*, unsigned int, unsigned int, float __vector(4)*)

    We have a crash that looks like this one using 2019.3.14f1 on mobile devices.
    Any idea?

    As I understand, сrash happens when realtime shadowing is turned on in multiple light sources.

    The issue still persists on 2019.3.10f1. This bug is critical to our project.

    We have the same issue. Our project is running on "com.unity.render-pipelines.universal": "7.1.6" and the LRP is not installed.
