Having struggled with the sortable plugin myself for the past few days, I think the following changes need to be done:

Add the helper function to create the correct sizes on the helper (draggable object) to have the correct size.
In the start function, add the item html to the placeholder html, to have the placeholder stay identical to the original.

Code:

$("#tbodyproject").sortable({
    items: "> tr",
    appendTo: "parent",
    helper: "clone",
    placeholder: "placeholder-style",
    start: function(event, ui) {
      $(this).find('.placeholder-style td:nth-child(2)').addClass('hidden-td')

      //copy item html to placeholder html

      ui.placeholder.html(ui.item.html());

      //hide the items but keep the height/width. 
      ui.placeholder.css('visibility', 'hidden');
    },
    stop: function(event, ui) {
        ui.item.css('display', '')
    },

    //add helper function to keep draggable object the same width
    helper: function(e, tr)
    {
        var $originals = tr.children();
        var $helper = tr.clone();
        $helper.children().each(function(index)
        {
        // Set helper cell sizes to match the original sizes
        $(this).width($originals.eq(index).width());
        });
        return $helper;
    },
    update: function( event, ui ) {
        let newOrder = $(this).sortable('toArray');
        $.ajax({
            type: "POST",
            url:'/admin/projects/updateOrder',
            data: {ids: newOrder}
        })
       .done(function( msg ) {
        location.reload();        
       });
    }
}).disableSelection();

You could try the approach in the snippet below.

$("#tabs").tabs();

$("#tbodyproject").sortable({
    items: "> tr",
    appendTo: "parent",
    helper: "clone",
    placeholder: "placeholder-style",
    start: function(event, ui) {
      ui.helper.css('display', 'table');
     // console.log(ui.placeholder.html())
    },
    stop: function(event, ui) {
        ui.item.css('display', '')
    },
    update: function( event, ui ) {
        let newOrder = $(this).sortable('toArray');
        $.ajax({
            type: "POST",
            url:'/admin/projects/updateOrder',
            data: {ids: newOrder}
        })
       .done(function( msg ) {
        location.reload();        
       });
    }
}).disableSelection();

When the placeholder is created, it only takes the number of cell in the row and create an empty row with those cells.

You are adding class hidden-td to nth child 2, so you are hiding one cell. This is OK for rows 2 and up, but not for first row, since you have one more cell in that row. See placeholder for row 2:

<td colspan="1">&nbsp;</td><td colspan="1" class="hidden-td">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td>

For first row:

<td colspan="1">&nbsp;</td><td colspan="1" class="hidden-td">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td><td colspan="1">&nbsp;</td>

What you can do is hide every cell in the placeholder and show only the number you need. This can be done with CSS, like this:

.placeholder-style td {
  display: none;
}

.placeholder-style td:nth-child(-n+7) {
  display: table-cell;
}
