title: PHP Artisan Tinker crashing from any command
body: <p>I haven't had this problem before, but my <code>php artisan tinker</code> crashes from issuing any command - and leaves no logs whatsoever on what is causing the crash.</p>
  
  <pre><code>project4 $ php artisan tinker
  Psy Shell v0.9.9 (PHP 7.3.0 — cli) by Justin Hileman
  &gt;&gt;&gt; use \App\Jobs\testJob;
  project4 $
  </code></pre>
  
  <p>or even the simplest command:</p>
  
  <pre><code>project4 $ php artisan tinker
  Psy Shell v0.9.9 (PHP 7.3.0 — cli) by Justin Hileman
  &gt;&gt;&gt; print("Hello World!");
  project4 $
  </code></pre>
  
  <p>I almost wonder if it isn't connecting to PHP correctly, but I can't find any logs anywhere. Laravel has no trace of the commands. I ran <code>brew update</code>, but no difference. For the record, <em>all</em> of my projects are affected. I can't <em>tinker</em> on any of my projects. Help!</p>
  
  <p>I did recently upgrade to PHP 7.3.0, which is working fine in every other area. Hmm...</p>
