Find depth of folder given the path in Powershell

I need to find how deep does the folder go at a given path. The issue is that the script refuses to work at all. It prints nothing not a single line.

$nmlfpEngD = "\\nml-fp\EngDesignLib\"
$nmlfPrdD = "\\nml-fp\PrdDesignLib\"
$csvFilePath = "\\nml-fp\Users\Scripts\Scripts\Aras\CSVOutput\GetSubFolders.csv"
$subfolders = Get-ChildItem -Path $nmlfpEngD*  -Directory -Recurse -Force
foreach ($subfolder in $subfolders) {
    $resultObject = [PSCustomObject]@{
        StringCount   = $subfolder.FullName.ToString().Split('\').Count
        SubfolderName = $subfolder.Name
        Path          = $subfolder.FullName
        #Exists = 1
    }
    $resultObject | Export-Csv -Path $csvFilePath -NoTypeInformation -Append
    Write-Host $resultObject
}

When Recurse is removed it gets the folder names at depth level 1. But this defeats the purpose. Is this not the correct use of Recurse?

Personally, I like using LiteralPath rather than Path on UNC paths, but that does not explain why your code fails to write to the file.
When using the -Recurse switch, there is no need to end the path with \*.

Also, I would use Select-Object here instead of a foreach loop and have it create the objects to collect in a variable using calculated properties.
Then write the whole thing out in one go to the CSV file.

Please try

$nmlfpEngD   = '\\nml-fp\EngDesignLib'
$nmlfPrdD    = '\\nml-fp\PrdDesignLib'
$csvFilePath = '\\nml-fp\Users\Scripts\Scripts\Aras\CSVOutput\GetSubFolders.csv'
$dirsep      = [System.IO.Path]::DirectorySeparatorChar

# you can give both paths to Get-ChildItem as array by simply adding a comma in between
$result = Get-ChildItem -LiteralPath $nmlfpEngD, $nmlfPrdD -Directory -Recurse | 
          # because these are UNC paths, we need to trim off the first two backslashes
          Select-Object @{Name = 'StringCount'; Expression = {$_.FullName.Trim($dirsep).Split($dirsep).Count}}, 
                        @{Name = 'SubfolderName'; Expression = {$_.Name}}, 
                        @{Name = 'Path'; Expression = {$_.FullName}}
# output on screen
$result | Format-Table -AutoSize

# output to Csv
$result | Export-Csv -LiteralPath $csvFilePath -NoTypeInformation
