looking back at excludes_5,

I had a code which highlights duplicates in red colour using the below code:

module 2 code:
Option Explicit


Sub sbFindDuplicatesInColumn_C()
Dim i As Long


'Declaring the lastRow variable as Long to store the last row value in the Column1
    Dim lastRow As Long


'matchFoundIndex is to store the match index values of the given value
    Dim matchFoundIndex As Long


'iCntr is to loop through all the records in the column 1 using For loop
    Dim iCntr As Long


'Finding the last row in the Column 1
    lastRow = Cells(Rows.Count, "A").End(xlUp).Row     'Range("A65000").End(xlUp).Row


'looping through the column1
    For iCntr = 1 To lastRow
        'checking if the cell is having any item, skipping if it is blank.
        If Cells(iCntr, 1) <> "" Then
            'getting match index number for the value of the cell
            matchFoundIndex = WorksheetFunction.Match(Cells(iCntr, 1), Range("A1:A" & lastRow), 0)
            'if the match index is not equals to current row number, then it is a duplicate value
            If iCntr <> matchFoundIndex Then
                'Printing the label in the column B
                 Cells(iCntr, 1).Interior.Color = RGB(255, 12, 0)
                 Cells(iCntr, 2) = "there are duplicates here!"
            End If
        End If
    Next
End Sub
For a path that is for example, 52 characters long the above code highlights duplicates in column 1. But, I have a path that is 611 characters long, and for some reason it does not detect duplicates OR highlights them, instead returns an error message:

run-time error 13: type mismatch, when I click debug it highlights "matchFoundIndex = WorksheetFunction.Match(Cells(iCntr, 1), Range("A1:A" & lastRow), 0)" in module 2

Main code in module 1:

Option Explicit


'>>>> this is for a path that is 52 characters long, including the long folder path prefix in the beginning
'>>>> duplicates are detected for this path (in column 1) and removed properly
'Const sPathTop As String = "\\?\C:\Users\abcde\Downloads\downloads abc 123 docs"


'>>>> this is for a path that is 611 characters long, including the long folder path prefix in the beginning
'>>>> duplicates are NOT detected for this path (in column 1) and gives run-time error 13: type mismatch, highlighting "highlighting matchFoundIndex = WorksheetFunction.Match(Cells(iCntr, 1), Range("A1:A" & lastRow), 0)" in module 2

I am not understanding why it would not highlight because i can list the folders with long folder path recursively without errors and I would think that highlighting doesn't depend on the number of characters in a string...what is the solution to this?
