Error getting files. The collection has not been initialized - powershell

Question

I am getting this error:
"Error getting files. The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested."
Code:
#Add references to SharePoint client assemblies
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")
[System.Reflection.Assembly]::LoadWithPartialName("WindowsBase")
#Variables
$SiteURL = "****************"
$LibraryName = "Documents"
$FolderName = "Customer Files"
Function Get-FilesFromFolder()
{
Try
{
#Load credentials of the admin account that has access to the library
$Cred = Get-Credential
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName, $Cred.Password)
#Building Context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = $Credentials
#Get the library
$Library = $Ctx.Web.Lists.GetByTitle($LibraryName)
$Folders = $Library.RootFolder.Folders
$Ctx.Load($Folders)
$Ctx.ExecuteQuery()
#Get the folder by name
$Folder = $Folders | Where {$_.Name -eq $FolderName}
$Ctx.Load($Folder)
$Ctx.ExecuteQuery()
#Iterate through each file
Foreach($File in $Folder.Files)
{
#Write out each file name
Write-Host "Now printing names for files in the folder."
Write-Host "There are "$Folder.ItemCount" files in the folder."
Write-Host -f Green $File.Name
}
}
Catch
{
Write-Host -f Red "Error getting files." $_.Exception.Message
}
}
All other guides I can find show examples of code missing "$Ctx.Load($Variable)", which I have, and I am stuck.
Hoping someone can see what I am missing - Thanks.
