HELP !!! Unity/C# Scripts don't run

Unity Engine
1

I put "Debug.Log(“Hello World”): in the update method. I attach my script to a cube in the scene. The Inspector shows that the script is attached. I click the run arrow. Nothing appears in the Console panel. I have reinstalled numerous times seeking any possible fix. No success. I have Unity running correctly (message appears in the console panel) on an older, dying, laptop but cannot get it to run correctly on my new laptop.
I am in Laguna Woods, CA, near LA. Anyone near LA I could visit, or visit me?? A Zoom session would be good.

I am stuck. Next option is to pay Unity $150 to look at my problem Any suggestions welcome. Harry

Is your Cube in the scene Active? Post your code here using code tags so we can have a look. Also, perhaps a screen shot of the inspector with the cube selected.
