#58870 issue: Updated the Check for isfile (path)

[Mehul-Lakhwani]

Here I updated the isfile check in the process where the code doesn't crashes in windows when the permission is denied it just simply ignore the file and assume that file doesn't exist and run the code further

It would be better to fix the underlying issue; see https://github.com/JuliaLang/julia/issues/58870#issuecomment-3237284417
