TypeError: Argument 1 passed to Drupal\webform\WebformRequest::__construct() [#2856635]

After updating the webfrom module from "8.x-5.0-beta5" to "8.x-5.0-beta7" (screenshot attached) I got the following error message:
TypeError: Argument 1 passed to Drupal\webform\WebformRequest::__construct() must be an instance of Symfony\Component\HttpFoundation\RequestStack, instance of Drupal\Core\Routing\RouteProv

And the website was completely broken. Unexpected error on every single page i was trying to open.
the drush command:
drush watchdog-list

helped me trace the error to the webform module.
After uninstalling the "webform" module, the site was working without any problems and the annoying "Unexpected error" gone away.

Did you clear the cache after the update?

So the cache would be cleared after the drush updb.

I think your WebformRequest class is literally out of sync. It should look like http://cgit.drupalcode.org/webform/tree/src/WebformRequest.php

Yes. Drush cleared the cache (one line before the end). See the attached screenshot.

All I did was install webform on my website about 1-2 months ago. And then I created a simple webform, just to see what are the differences in Drupal 8.
Haven't done anything else since then.

Try installing 8.x-5.0-beta5 then make a simple webform. After that perform the update.
