Error when editing custom post type with non-Latin slug in Gutenberg: "You attempted to edit an item that doesn't exist."

Description

When attempting to edit a custom post type with a Persian slug in the Gutenberg editor, I encounter the error message:

"You attempted to edit an item that doesn't exist. Perhaps it was deleted?"

The post is still accessible via its URL, and no data appears to be lost. This issue seems to be related to the handling of slugs containing non-Latin characters in the Gutenberg editor.

Step-by-step reproduction instructions

Create a custom post type (CPT) with a Persian slug.
Example: my_custom_post_type with a slug like ویدیو (or any Persian characters).
Permalink structure should be /%postname%/ .
Publish a post in that CPT.
Attempt to edit the post using the Gutenberg editor by navigating to the post editing screen.

The error message "You attempted to edit an item that doesn't exist" appears.


$video_labels = array(
        'name'                => _x('Videos', 'Post Type General Name', 'test'),
        'singular_name'       => _x('Video', 'Post Type Singular Name', 'test'),
        'menu_name'           => __('Videos', 'test'),
        'parent_item_colon'   => __('Video :', 'test'),
        'all_items'           => __('All Videos', 'test'),
        'view_item'           => __('View Video', 'test'),
        'add_new_item'        => __('Add Video', 'test'),
        'add_new'             => __('Add Video', 'test'),

        'not_found_in_trash'  => __('No Video Found In Trash', 'test'),
    );

    // Register Video Post Type

            'labels'        => $video_labels,

            'menu_icon'     => 'dashicons-video-alt3',
            'menu_position' => 5
        )
    );
