Apologies, it was an error in my code!

Add the below to your functions file:

function project_excerpt() {
	global $post;
	$text = get_field('objetivos');
	if ( $text ) {
		$text = strip_shortcodes( $text );
		$text = str_replace(']]>', ']]>>', $text);
		$text_length = strlen($text); // Get text length (characters)
		$excerpt_length = 50; // 50 desired characters
		$excerpt_more = '…';

		// Shorten the text
		$text = substr($text, 0, $excerpt_length);

		// If the text is more than 50 characters, append $excerpt_more
		if ($text_length > $excerpt_length) {
			$text .= $excerpt_more;
		}

	}
	return $text;
}
add_shortcode('custom_acf_excerpt', 'project_excerpt');

This assumes 2 things:
1) The field name is actually a lower case o (not the label which is probably uppercase O)
2) It’s a standalone field i.e. not in a flexi layout, gutenberg block etc.
3) In your Elementor editor, you can add shortcodes

If you can, simply add
[custom_acf_excerpt]

I’ve just added Objetivos field to a fresh WP install.
I then added text to the field
As it’s using the twenty-twentyone theme, I added a shortcode widget into the Gutenberg editor, I then added [custom_acf_excerpt]
It displayed the truncated text I’d used.
