Deletion of NewForm.aspx

Hi,

I have accidentally deleted the NewForm.aspx from one of our lists which happens to be in the classic experience. I have tried to restore it from the recycle bin but i could not locate it in the Site Collection recycle bin. I have aldo tried to create one via sharepoint designer 2013 but i get a "Could not save changes to the server" .

Is there any other way to perhaps restore/retrieve the above mentioned form or creating a new one
