Resolve-Path: cannot find path because it does not exist. error in powershell

Question

Firstly: what My code does it counts the number of duplicate files in a particular path entered by the user. It does this by first calculating which files have the same length. and from the files that have the same length, it checks which files also have the same hash. And then in the end I am making an object which contains the information that I need to print in a table.

Problem: In my code,

1. I am getting an error which I am pretty sure is coming from the Get-FileHash commandlet. when I ctrl + click on the link that is given in the "At" section of the error, It takes me to the Get-FileHash commandlet utility in powershell C: >WIndows > system32 > WindowsPowershell > v1.0 > Modules > Microsoft.Powershell.Utility > Microsoft.Powershell.Utility.psm1 > Get-FileHash{}

2. the error only comes up for some .msg and .pdf files

3. the code works perfectly fine on a path with lesser files.

Here is the Error:

Resolve-Path : Cannot find path '<path of File>' because it does not exist.

And here is the code:

Any advice to remove this error will be appreciated.
