when I click yes the window goes blank and stays blank.
I've not experienced that recently. But when I've had in occur in the past it was either a screen font size or resolution setting.
On Windows 10 go into settings and then go into System. For Display, make sure scale and layout is set to 100% and that your display resolution is set to whatever is "recommended" for your graphics card/monitor setup. If you have to change any of those settings, reboot before checking to see if it helped.
