A few days ago, I updated to v1809. I have since installed updates as well.
The issue is that any attempt to use the Microsoft Office 365 feature of "Microsoft Print to PDF" from Edge, or to save an image from the Snippet Tool causes the following error:
This is applies to only new attempts to create the file (when Print to PDF used), and the message is slightly different for attempts to save from Snipping tool (e.g. \Pictures\ and not \Documents\.) Both have the identical message "File not found."
This is occurs regardless of in-use profile (Admin, my MS Account (Users group), my local Standard Profile (Users group), etc.) Does not appear to be related to profile settings or type.
I have followed a number of recommended approaches to fix the issue (reset Edge, set to default for printer, etc.) w/o success.
Search on the net proved fruitless.
My Office 365 subscription reports "Up to date" for all updates.
Any guidance or help is greatly appreciated!
