Press the Windows key + Shift + Ctrl + B at the same time. This should bring the screen back. Then apply any Windows updates.
If this does not work, see the following Microsoft link for more information: Toubleshoot black screen or blank screen errors in Windows 10
Starting the PC in safe mode can help narrow down the issue. Safe mode loads default settings and basic device drivers. See Start your PC in safe mode in Windows 10 or Windows 11 for more information.
