Answer 1

You can edit the file /usr/share/phpmyadmin/libraries/DisplayResults.php

in the specific line #XXXX Search $col_visib[$j] and add ?? false

$col_visib[$j] ?? false

in your case

list($order_link, $sorted_header_html)
    = $this->_getOrderLinkAndSortedHeaderHtml(
        $fields_meta[$i], $sort_expression,
        $sort_expression_nodirection, $i, $unsorted_sql_query,
        $session_max_rows, $comments,
        $sort_direction, $col_visib,
        $col_visib[$j] ?? false
    );

Ps. On Debian works also

have fun
