Newbe need help - TAB completion not working

I am new to all this. I have installed the latest version of Anaconda on Windows 10 laptop - ASUS Vivobook 15. I am taking a course and have been stuck for over a week because the TAB completion in Jupyter Notebook is not working. For example when I type day. and press my tab key nothing opens / nothing happens. I have tried several suggestions I found on the web but nothing works.
I have the following versions installed
conda 22.11.1
Python 3.9.13
ipython –version = 7.31.1
any help is greatly appreciated as I have tried most of the solution I see on the web.
