    Restarting Unity after creating the project fixes the issue.

    Issue exists in beta 3 as well. This is a blocking bug.

    Issue still present in 2019.3.0b2.
    Reproducible by simply creating a new project in 2019.3.0b2 via Unity Hub and selecting the High Definition RP Template, 22 of these errors will be logged right away in the Editor.
