Glad that is solved your problem.
Like I said earlier in my reply, I’d urge you to look at it as a configuration difference. In the example that you’re following, the reason for failure isn’t the wrong property being set on Type Into but the selector itself is different.
This can happen on different computers and there are different reasons for this to happen.
Selector from the downloaded example:

If you compare the elements in the ‘Edit Selector’ section on these screenshots, you’ll notice that my computer couldn’t see the property
aaname='Text Editor' in the second row, which is why the selector shows invalid.
If you are yet to reach the ‘Selectors’ in your training, I understand your frustration. But, UiPath forum is a great place to get help with specific issues such as this one. I wish you all the best with your training
