    Since updating to 2019.4.12, I keep getting this console error occasionally in play mode:

    I've already tried Layout -> Revert Factory Settings, and restarted Unity but I'm still seeing the error.

    Anyone know if this is a regression in the latest 2019 LTS version? Or if that's just a coincidence? I'm not finding any other approaches to resolving this. Here's what my layout looks like: It's just standard Unity windows, plus ProBuilder:

    Same issue, and also the scene view is blank in the project for some scenes (though these scenes will still play, and the game view is populated). Unity editor gives the following error when I try to switch layouts (using: Window > Layouts > Default) or revert windows to factory settings:

    ArgumentNullException: Value cannot be null.
    Parameter name: dest

    Same here, restarting the Layout only lasts for 1 session.

    Have this issue. Resetting layout helps only until next restart.

    I filled a bug report (Help > Report a bug...). I suggest that all of you also do this so they can see the issue and fix it.
