Execution Stuck at Get-PnPPage if function executed on Button Click

Question

Powershell Version: 7.4.1 PnP version: PnP.PowerShell 2.4.0 I am trying to create pages from Sharepoint template using following function.

function New-ArticlePage {
    param (
        $PageName,
        $PageTitle,
        $PageSubHeader
    )
    $TemplateURL = "Templates/article-template.aspx"
    
    Connect-PnPOnline -Url $SharepointSite -Interactive
    $Template = Get-PnPPage -Identity $TemplateURL  
    Remove-PnPPage -Identity $PageName -Force
    $Template.Save($PageName) 
    Set-PnPPage -Identity $PageName -Title $PageTitle | out-null
    Set-PnPPageTextPart -Page $PageName -InstanceId 1fca516d-4584-448d-8fff-2c0d5ab10318 -Text PageSubHeader

}

If I execute the function from a Button click event, the execution halts at following line

$Template = Get-PnPPage -Identity $TemplateURL  

Button code:

$Button_CreatePage = New-Object System.Windows.Forms.Button
    $Button_CreatePage.Location = New-Object System.Drawing.Point(100,335) 
    $Button_CreatePage.Size = New-Object System.Drawing.Size(195,23)
    $Button_CreatePage.Text = "Create Page"
    $Groupbox_ArticleTemplateModel.Controls.Add($Button_CreatePage)
    $Button_CreatePage.Add_Click(
        {
            New-ArticlePage -PageName $Textbox_PageName.Text -PageTitle $Textbox_PageTitle.Text -PageSubHeader $Textbox_PageSubHeader.Text
        }
    )

If I execute the function directly with params it creates page as expected. But if I place the same code inside Add_click function it halts at Get-PnPPage -Identity $TemplateURL

New-ArticlePage -PageName $PageName -PageTitle $PageTitle -PageSubHeader $PageSubHeader
