Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I was having the same issue. Repairing the office installation did not help. First, I ran a windows update. Second, I updated all of my intel drivers from intel's website. And lastly, I rebooted after the updates and the office 365 start screen was working correctly. I hope this helps everyone.
I am running an Asus Vivobook with i7-10510U CPU and Intel UHD Graphics
