Update: October 11, 2018
Microsoft has isolated the cause of the Windows 10 v11809 update bug and is rolling out a fix to members of the Windows Insider Program.
Microsoft claims the number of impacted customers was small — "reports of data loss" limited to "one one-hundredth of one percent of version 1809 installs."
Microsoft has fully investigated the issues and has resolved all the scenarios where data could be lost, keeping all files in the original folder location and relocated folder intact. Microsoft will offer data recovery options but cannot guarantee the outcome of any recovery efforts.
