I'm getting error in switch statement inside scriptblock. Option 1 is executing but 2 and 3 doesn't work.

$server = Read-Host -Prompt 'Enter the server name:'

$cred   = Get-Credential



$choice = {

    Param([int]$opt)



    switch ($opt) {

        1 {

            Set-ExecutionPolicy Remotesigned -Force

            $EP = Get-ExecutionPolicy

            echo "Executionpolicy:$EP"

        }

        2 {

            Restart-Service WinRM

            $RM = Get-Service WinRM | Select Status

            $RM = $RM.Status

            $RMT = Test-WSMan

            echo "WinRM status: $RM"

            echo "Testing WSMan......"

            $RMT

        }

        3 {

            Set-ExecutionPolicy Remotesigned -Force

            Restart-Service WinRM

            $RM = Get-Service WinRM | Select Status

            $RM = $RM.Status

            $EP = Get-ExecutionPolicy

            echo "WinRM status: $RM"

            echo "Executionpolicy:$EP"

            $RMT = Test-WSMan

            echo "Testing WSMan......"

            $RMT

        }

    }

    Exit-PSSession

} 



if (Test-Connection $server -Quiet) {

    $session = New-PSSession -ComputerName $server -Authentication Default -Credential $cred

    Invoke-Command -Session $session -ScriptBlock {

        $EP = Get-ExecutionPolicy
