Time and date sliders don't change values in text boxes

When you turn on shadows in a model, and then drag the sliders to change the time and date, the shadows change as expected but the time and date in the text boxes don’t change. They’re stuck on 12:00am and 01/01. If I try to manually enter a time or date in the text box, when I tab out of the box, SketchUp crashes. Happens on MacOS 10.13, Chrome 86.0.4240.75. Also happens in the current version of Firefox.
