Tab Key Not Working

Good day, @PVSI.

Thanks for sharing the troubleshooting that you've made to address the concern. 

The issue might be with the keyboard itself. This can be the reason why you're still getting the same behavior after using the Rebuild Data tool and using a new computer. 

Let's fix it by carefully turning the keyboard or laptop upside down and gently shake it. Usually, anything beneath the keys or inside the keyboard will shake out of the device, freeing up the keys for effective functioning once again.

You can also open another application on your computer and test if you're getting a similar result. If so, try using another keyboard or buy a new one to address the issue.
