<?php

use Carbon_Fields\Block;
use Carbon_Fields\Field;

Block::make("crb_test", "TEST")
    ->add_fields(array(
        Field::make('rich_text', 'crb_text', "Content")
            ->set_width(100)
    ))
    ->set_mode('preview')
    ->set_category('theme-blocks')
    ->set_render_callback(function ($fields, $attributes, $inner_blocks) {
?>
    <div>
        <?= $fields['crb_text']; ?>
    </div>
<?php

Steps to Reproduce the Problem

1. Create a page with crb_test block inside
2. Fill text inside rich text. Check for the paragraph tag in text tab
3. Call wp_update_post with post_content of created post
4. Reload created page

I'm used this snipped for checking wp_update_post behavior. functions.php

add_action('init', function () {
    $check = isset($_GET['test']);
    if (!$check) {
        return;
    }
    $created_post_id = 1245;
    $post = get_post($created_post_id);
    echo esc_html($post->post_content);

    if (has_blocks($post->post_content)) {
        wp_update_post([
            'ID' => $post->ID,
            'post_content' => $post->post_content
        ]);
    }

    echo "<br>";
    $post = get_post($created_post_id);
    echo esc_html($post->post_content);

    exit(200);
});
