Latest wordpress still has this bug
​https://wordpress.stackexchange.com/a/409087

I would suggest to use something like

<?php
                if(! ($value instanceof Countable)){
                        $stop = 0;
                }else{
                        $stop    = count( $textarr ); // Loop stuff.
                }

Sorry forget to say this is in wp-includes/formatting.php around line 3840
