Try using Dell's website customized AMD drivers and see if it works for your laptop. Also completely uninstall all AMD drivers thru Windows Control Panel -Uninstall panel and then using DDU (latest version) in safe mode. Then reinstall the Dell website driver package and see if it works.
Plus you need to mention what type of GPU your laptop uses and which version of Windows. It has been mentioned in the past, that Windows should be completely updated with no new updates thru Windows Update before installing any AMD drivers.
Oops, you did mention Windows 10 in title with your GPU type.
