    When filtering for allowed block types, return the boolean for the post types you are not restricting. Otherwise, it won’t work as Nilambar’s example because $allowed_block_types is expecting an array or a boolean.
    This worked for me when filtering allowed blocks for a custom post type. You’ll want to substitute ‘myplugin’ with your namespace and the post types you’re filtering in the switch statement.

    function myplugin_allowed_block_types( $allowed_block_types, $post ) {
	
	switch( $post->post_type ) {
        case 'my_cpt_1':
            return array( 'core/paragraph' );
            break;
        case 'my_cpt_2':
            return array( 'core/paragraph', 'core/heading' );
            break;
        default:
            return true;
    }

    return $allowed_block_types;

}
add_filter( 'allowed_block_types', 'myplugin_allowed_block_types', 10, 2 );

    This allows only paragraph block for post.

    function wpdocs_allowed_block_types( $allowed_block_types, $post ) {
    if ( $post->post_type !== 'post' ) {
        return $allowed_block_types;
    }

    return array( 'core/paragraph' );
}

add_filter( 'allowed_block_types', 'wpdocs_allowed_block_types', 10, 2 );
