We tried modifying the view in SharePoint 2010 using Designer 2010 and it’s corrupted! No option to delete the view !
Spin up your SharePoint Shell Management and execute the below code
$SPWeb = Get-SPWeb $WebUrl
$List = $SPWeb.Lists[$ListName]
$View = $List.Views[$ViewName]
Note: Ensure the View you are removing. Cross check by it’s ID [GUID]
