From https://dlang.org/library/std/path/is_valid_path.html :

It does *not* check whether the path points to an existing file 
or directory; use std.file.exists for this purpose.


You are using the wrong function for the job.

The simple explanation is that the path you specified doesn't 
actually exist.

Looks like its a bug with WinAPI.
