how could I press cancel on the select file window and have the program restart in powershell

I have a button in my program that lets the user select a file from their computer however I would like to make it so when they press the cancel button it restarts the entire program. Any help on this would be greatly appreciated because I have been struggling with this for a while. This is what I have so far...

function SelectDrive($title)
if($global:FirstDrive -eq $null)
$DriveSelection = New-Object System.Windows.Forms.FolderBrowserDialog
$DriveSelection.Description = $title
# $DriveSelection.rootfolder = "MyComputer"
[void]$DriveSelection.ShowDialog()
$global:FirstDrive = $DriveSelection.SelectedPath

else
removeAll
initVal
$FillError.text = ""
$mainForm.controls.AddRange(@($StartUSB,$StartDualMedia,$SelectOne,$USBLabel,$2USBLabel))
$mainForm.refresh()

if ($ClickedButton -eq 'Cancel')
Start-Process powershell.exe -ArgumentList "-File $($MyInvocation.MyCommand.Definition)"
Exit
