### Issue Details

* **Electron Version:**
  * 8.0.0-beta.5
* **Operating System:**
  * Windows 10
* **Last Known Working Electron version:**
  * 8.0.0-beta,4

### Expected Behavior
http://google.com should load without any crash

### Actual Behavior
Going to http://google.com works for the first time. However, when going to the same URL after the cache has been saved in `userData`, it crashes with `3221225477` exit code. The strange thing is that when going to https://google.com, it works perfectly.

### To Reproduce
(I couldn't use Fiddle, since it saves the `userData` temporarily)
