Cannot load xltx template with conditional formatting or table used anywhere

[Max-Kolodezniy]

Hi to all!

Im trying to open existing template for avoid building workbook from scratch.
It's impossible to load the template if conditional style or table was used. Source templates attached templates.zip

<?php
/*
 * @file PhpSpreadsheet-master/samples/test.php
 */

require __DIR__ . '/Header.php';

// $template = __DIR__ . '/../template_no_issues.xltx';
// $template = __DIR__ . '/../template_bug_table.xltx';
$template = __DIR__ . '/../template_bug_conditional_formatting.xltx';
$output = __DIR__ . '/../workbook_' . date('d_m_Y_H_i_s') . '.xlsx';

// Create temporary file that will be read
$helper->log('Create new Spreadsheet object from ' . $template . ' template');
$callStartTime = microtime(true);
$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($template);
$helper->logRead('Excel2007', $template, $callStartTime);

// Export to Excel2007 (.xlsx)
$helper->log('Write to Excel format');
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Excel2007');
$callStartTime = microtime(true);
$writer->save($output);
$helper->logWrite($writer, $output, $callStartTime);

Error log:
