I think you should add an additional check on line 69 of file class-acf-form-shortcode-public.php.
In some specific cases I was getting this message "PHP Notice: Trying to get property 'post_content' of non-object in /var/www/html/wp-content/plugins/acf-form-shortcode-master/public/class-acf-form-shortcode-public.php on line 69"
I changed line 69 from...
if( has_shortcode( $post->post_content, 'show_acf_form' ) ){
to...
if( isset($post->post_content) && has_shortcode( $post->post_content, 'show_acf_form' ) ){
... and the error message is gone.
