    Since updating to 2019.3.0b5 I endlessly get this error:

    Code (CSharp):
    1. Exception: No pending assemblies queued for compilation and no compilers running. Compilation will never finish.

    Could you report a bug on this?

    This exception should never be emitted and shows that there is a bug in the compilation pipeline. We would need a repro project in order to be able to fix it.

    Deleting parts of my Library cleared the error so I can't reproduce it alas.

    I also get this after every Unity 2019.3.bx upgrade....

    Exception: No pending assemblies queued for compilation and no compilers running. Compilation will never finish.
    etc...

    Followed by
    Assembly with cyclic references detected (Packages/com.unity.cinemachine/Runtime/com.unity.cinemachine.asmdef)
    Assembly with cyclic references detected (Packages/com.unity.render-pipelines.universal/Runtime/Unity.RenderPipelines.Universal.Runtime.asmdef)

    So anything URP related is unusable in 2019.3.bx since the scripts fail to load / work.
    Creating URP assets is not accessible anymore.

    It would be very helpful if you could submit a bug report with a minimal reproduction project for this issue.

    This is a known issue and we're working on a fix. Related forum thread: https://forum.unity.com/threads/can...universal-rp-and-unity-2019-3-0b7-0b9.771629/
