Hi
I had occasion to reinstall Office 2019 in the past and I lost my Address book.
If you have Office 2019 Professional, it is activated via your license email account, do you lose this license email account?
You may follow the steps in article: Error 0xC0000142 when you start an Office application.
If updating and repairing Office are ineffective, you still need to reinstall Office, but this license account is required for Office activation.
Besides, according to the error message "cannot verify the license, you should use the repair function in the Control Panel", it seems that there is something wrong with your Office activation at the beginning.
Please make sure that apart from Office 2019, there are no other Office products on the computer, such as Visio, Project, etc.
