We found something that may help. Your video, on the command line you have only one line of prompt history showing. So when the AREA command goes to report the AREA you cannot see it. The command tries to display the total area at the mouse crosshair. Then when Dynamic Dimensions are enabled, it overrides that pop up at the crosshair and so you end up not observing the Area reported anywhere.
So turn off Dynamic Dimensions down near the Osnap toggle buttons. On the command line palette, is a wrench symbol containing the command line settings. In the settings is "Lines of prompt history." Default value is to have 3 lines. Let's see if those changes help.
