title: Angular 9.0 ngserve throwing "Invalid Token" errors in vendor.js file
body: <p>I just updated to Angular 9, and when I try to run ngserve I'm getting &quot;Uncaught SyntaxError: Invalid or unexpected token&quot; errors in the vendor.js file. I've now gotten this error multiple times, usually on different lines of the vendor.js file (first on Line 35xxx, then on Line 15xxx, and now on Line 7xxx). Inspecting that file in the browser always shows some &quot;�&quot; characters where I would expect legible characters, so it seems the ngserve process might be running into problems while generating that file, and inserting incorrect/garbage characters? This latest example is on Line 7618 of vendor.js, and the Chrome network inspector shows that line as:</p>
  <pre><code>return new _angular_animations__WEBPACK_IMPORTED_MODULE_0__[&quot;NoopAnimationPlayer&quot;](timelineInstruction.duration, �BC�\��Instruction.delay);
  </code></pre>
  <p>I have no idea where to begin for fixing this issue. It's completely preventing my website from loading, so I'm basically stuck.</p>
