I recently ran an into an issue on build machine recently that resulted in a similar issue.
Logstash has some very long path names, and can exceed the 260 character limit of Windows.
Assuming you have the most recent updates to Windows 10, you may try set this to 1
HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled
