listdir exception on Windows share

[kalemas]

Hi, we encounter following issue if Library is hosted on windows share if there is no permission to list root folder:

I m not sure the reasons it occur and how it should be handled, @krathjen do you?

@krathjen We reverted our storage settings and issue came back (( it is so wired as get different errors under debugger and runtime.

This error i getting when starting studioibrary as usual

and this strange behavior when i run under debugger, first evaluation throw OSError but subsequent - PermissionError 8^S

[kalemas]

and this again in production mode((

With #441 issue is gone, but i still do not understand the reasons why it happen.
