[Resolved] Issue Changing Default Language to German

Problem:
If you're experiencing issues with your website loading indefinitely after changing the default language to German, while it works fine when set to English, we have identified a potential solution.
Solution:
We recommend modifying a specific piece of code in the YITH WooCommerce Product Bundles Premium plugin. Please navigate to

/wp-content/plugins/yith-woocommerce-product-bundles-premium/includes/objects/class.yith-wc-product-bundle-premium.php

and locate the code at line 186. Change the existing code from:

if ( isset( $sitepress ) ) {
    $found = false;
 
    $details = $sitepress->get_element_language_details( $id );
    if ( $details->trid ) {
        $current_id  = absint( $details->trid );
        $bundle_data = get_post_meta( $current_id, '_yith_wcpb_bundle_data', true );
        if ( !! $bundle_data ) {
            $id    = $current_id;
            $found = true;
        }
    }

to:

if ( isset( $sitepress ) ) {
    $found = false;
 
    $details = $sitepress->get_element_language_details( $id );
    if ( $details->element_id ) {
        $current_id  = absint( $details->element_id );
        $bundle_data = get_post_meta( $current_id, '_yith_wcpb_bundle_data', true );
        if ( !! $bundle_data ) {
            $id    = $current_id;
            $found = true;
        }
    }
