First update the graphics driver. I would download DDU and get rid of any remnants from previous drivers. And then download and install your graphics driver directly from the link below.

DDU can be downloaded from:

The black screen issue could be related to display drivers installed.
If the drivers are corrupted or incorrect drivers were used, the display won't work properly.
Try a different version or perform a clean drivers installation using DDU
Download the latest drivers from AMD.
Uninstall the current drivers in safe mode with DDU, reboot and install the latest drivers.

If that doesn't fix the issue do a restor to a restore point before the problem, and then reinstall the graphics driver again.

If that doesn't help the next stage yould be to do a Windows 10 Repair upgrade using your Windows 10 installation media ( or you can download a Windows 10 ISO).

And if that doesn't fix the issue, do fresh install of Windows 10.

Here are instructions on downloading an Windows 10 ISO and using the Repair Upgrade tool.
