Hi!
You must forces WordPress to load wp-block-library by adding add_theme_support( 'wp-block-styles' );
no way… only broken with blocks (block columns, block cover, block cart,etc…)
If I understand correctly, the styles are only missing for individual blocks? Or are there no styles at all?
Have you enqueued your individual styles in functions.php using the hook enqueue_block_editor_assets?
all kind of blocks loaded used in block editor. if I use the wp-block-columns, wp-block-cover, the block-cart, the block-checkout (in woocommerce)… no css is loaded
Since we don’t know your custom theme, it’s difficult to say anything more specific. You would have to see what you need to adjust in it so that the styles are reloaded. The line mentioned above, add_theme_support( ‘wp-block-styles’ );, would be important for this.
Please check the developer console of your browser to see if there are any error messages if you load the editor.
Also, please check Tools > Site Health to see if there are any abnormalities.
You are also welcome to provide your theme, especially the functions.php, so that we can assist you if necessary. You can do this on gists, for example: https://gist.github.com/
