It turns out that disabling the Intel and Nvidia drivers on my Windows notebook computer are not really sufficient to fix the issue when Visual Studio 2017 launches to a black or invisible screen, as by doing this, I lost the ability to connect an external monitor to the HDMI port on the computer. Super bummer.
A bit more digging through the interwebs led me to this answer to a question on Stack Overflow:
White screen while opening visual studio
Basically, I re-enabled the Intel and Nvidia display options, then opened the Nvidia Control Panel by right-clicking on the desktop, selected Manage 3D Settings and changed the Preferred graphics processor selection from Auto-select to High-performance NVIDIA processor. Now everything is back to working the way I would like it to.
BTW, there are no birthdays today worthy of mention (cough, cough), so Happy International Left Handers Day!
