Need help with Microsoft Office install that won't start

We have a customer with a brand new Lenovo laptop and running Office 2019 Pro Plus. After some driver updates, Outlook and Word will not start. We have tried everything: - Safemode - Repair (both offline and online) - Uninstall and re-install - Registry changes on youtube It simply will not install. We need you to remote it and fix it. We have lost the licence after all the re-installment, so you might need to get a new licence for us. We need this fixed today!
