    Ugh. Figured it out and not surprisingly it was due to the "Substance in Unity" Plugin. Have had numerous issues with this plugin breaking the editor.

    Both plugin versions 2.4.5 and 2.5.4 cause this issue.

    Still getting this issue in 2021.1.6 and 2021.1.7. Weirdly enough, it doesn't happen on a brand new URP project.
