You have to modify at this code

$this->_subCategory = $nodes['category-node-' . $this->getValue()];

to

    if(isset($nodes['category-node-' . $this->getValue()])){
        $this->_subCategory = $nodes['category-node-' . $this->getValue()];
    }

Some value does not exits at $nodes arra that why it is creating issue.

After some time our developer found a solution.

The reason is a bug in the big menue extension. If a category got deleted by accident it is still looking for the not existing child category.

Solution is to deactivated and than activate the parent category of the missing child category. Than it should work.

please find more detailed information how to reproduce and solve it in our blog https://www.konvis.de/neuigkeiten/magento/magento-2-magetique-template-big-menue-bug-and-solution-en/

This solution fixes it forever. Basically, if category doesnt exist, just don't show it.

app/code/TemplateMonster/Megamenu/view/frontend/templates/html/topmenu/block/row/column/category.phtml

<?php
$category = $this->getCategory();
if ($category) {
    $subCategories = $category->getChildren()->getIterator();
    //$showSubcategories = $this->getShowSubcategories($category);
    //$numberOfSubcategories = $this->getNumberOfSubcategories($category);
    $cssClass = $this->getCssClass($category);
    $image    = $this->getImage($category);

    ?>
    <ul class="mm-submenu level1">
        <li class="item<?php echo $cssClass; ?> ui-menu-item">
            <?php if ($image) : ?>
                <span class="mm-image"><img src="<?php echo $image; ?>" alt=""></span>
            <?php endif; ?>
            <a href="<?php echo $category->getUrl(); ?>">
                <?php if ($label = $category->getMmLabel()): ?>

                <?php endif; ?>
                <?php echo $category->getName() ?>
            </a>
            <ul class="mm-submenu level2">
