Exception: Argument 1 passed to OCA\External\AppInfo\Application::OCA\External\AppInfo\{closure}() must be an instance of Symfony\Component\EventDispatcher\GenericEvent #179
Description
Steps to reproduce
I have 6 identical instances on a root server, all installed via Ansible, so the code base is exactly the same. All 6 instances got upgraded from latest version 17 to version 18 and 5 of those instances work OK, just one has an issue in the files app. After logging in, an internal server error is indicated and looking into the log shows this stack trace 3 times for each request:
Error index Exception: Argument 1 passed to OCA\External\AppInfo\Application::OCA\External\AppInfo\{closure}() must be an instance of Symfony\Component\EventDispatcher\GenericEvent, instance of OCP\EventDispatcher\GenericEvent 2020-02-01T11:49:02+00:00

Yes, I have completely wiped the installation and started from scratch, not success. And what's interesting, both the desktop client and the Android app can show the files correctly.
When going to a different app, i.e. calendar or deck, the instance works just fine. This only happens on the files app.
I also rescanned all files and group_folders from the console with occ, no change either.
So I guess something with the database must be causing this issue and maybe the class declaration of one of the PHP files is not quite as accurate as it should be for PHP 7.2
