Question Input System Properties doesn't appear

Hello all,
I'm a bit of a newbie when it comes to Unity and programming in general.
I was following a tutorial on creating an input system through input action. but when I go and add an action map the properties option does not show [see attached image], I'm also greeted with the huge error message below.

If anyone familiar with this problem please help, I'm under deadlines to finish this course and I keep getting trampled by errors that I can't find solutions for.

Thanks.

I am looking at the same error as well.

Unity 2020.3.12f1 on InputSystem 1.0.2

AND...... UPDATE!!!

I read somewhere that having virtual joysticks drivers installed would mess up Unity's input system.

I indeed have a virtual joystick driver installed (called "vjoy") so I went ahead to remove it and restarted my computer. Then the "Property" of the input action window returns.
