Check out the Windows 10 forum
It deals with some who have had problems like you describe.
It sounds like this just happened on the 25th but it was ok before.
I wonder of the Win10 Windows Updates are a factor.
I don't have Win10 you could consider a system restore
I'd like to mention I do a monthly system image backup before Windows Updates are due on my Win7 & Win8 computers. Consider doing so on your Win10 computer
Can’t tell since the issues don’t seem to include your problem but coincidentally
Microsoft reverses course, restores downloads of Windows 10 November Update
It appears to me you had no problems on Nov 24 but Nov 25 changed that
Are you still having the same problem today Nov 28?
