Shortcode Rendering Issue After WordPress Update with block_template_part()

[IonPulbere]

Description

Hi,

We recently performed an update on our WordPress website to the latest
version, 6.4.3. However, we have encountered an issue where the shortcodes
are not rendering as expected.

This problem specifically arises when the shortcodes are added in the
block template and an attempt is made to display them using
block_template_part(). It's worth mentioning that the shortcodes were
rendering successfully on WordPress version 6.2.

See images attached:
1)WP 6.4.3 -
2)WP 6.2 -

Could you please investigate and provide a solution for this issue at your
earliest convenience? Your prompt attention to this matter would be highly
appreciated.

Thank you for your assistance.

Best regards,
Ion

Step-by-step reproduction instructions

1. Create a custom template part, for example, "my-dash.html" on the path (\wp-content\themes\twentytwentyfour\parts\my-dash.html)
2. In the WordPress backend, access /wp-admin/site-editor.php
3. Navigate to "Patterns/Manage all templates part."
4. Select the "My Dash" template part.
5. Add a shortcode element (add any desired shortcode)
6. In the theme files, call the template part from a custom PHP file using block_template_part("my-dash"). For example, I used the following file path: \wp-content\themes\twentytwentyfour\woocommerce\myaccount\dashboard.php.

Thanks for creating the issue, @IonPulbere.

I believe this is a duplicate of https://core.trac.wordpress.org/ticket/56780. Core PR - WordPress/wordpress-develop#3851.

@IonPulbere This is not fixed - can you confirm with the newest Wordpress?

For anyone struggling this may work for you:

add_filter('render_block_core/shortcode', function(string $block_content): string {
    return do_shortcode($block_content);
});

add_filter('render_block_core/shortcode', function(string $block_content): string {
return do_shortcode($block_content);
});

Worked for me. THANK YOU!
