WordPress cannot download SVG files

Cannot download SVG files with WordPress 6.6.2 / works with 6.0.9 version

I have no SVG plugins installed. A blank page opens systematically (‘about:blank#blocked’)
No errors in logs

functions.php

add_action('after_setup_theme', function () {
add_theme_support('title-tag');
add_theme_support('menus');
add_theme_support('html5', array('comment-list', 'comment-form', 'search-form', 'gallery', 'caption', 'style', 'script'));
add_theme_support('post-thumbnails');
});

add_filter('upload_mimes', function ($mimes) {
$mimes['svg'] = 'image/svg+xml';
return $mimes;
});
