Whitepage on product with 27 variations

Hi,

I have a product with 27 variations. When I try to load the page, it shows only white page. When I disable the plugin, the product is loaded. On products with fewer variations it works. Any idea how to fix it? Maybe I can deaktivate the plugin only for this single product?
Using chatgpt I tried to do this, but without success:

add_action( ‘wp’, function() {
$product_id_to_disable = 26939;

if ( is_product() && get_the_ID() == $product_id_to_disable ) {
add_filter( ‘disable_woo_variation_gallery’, ‘__return_true’ );
}
});

Thanks and regards,
Steffen
