"no app in context" after update 13.0.1 -> 13.0.4

I would have used your template but most sections I can not fill in, because I could not login anymore. sorry.

Steps

I have just updated nextcloud from 13.0.1 to 13.0.4 via the update button. And directly before the "themes" plugin.

If I want to login now this fails: "The page isn't redirecting properly".
The nextcloud.log file says (extract):

app":"no app in context",
"method":"GET","url":"/index.php/apps/files/",
"message":
Exception":"Error",
    "Message":"Class 'OCA Files App' not found",
    "Code":0,
    "Trace":
      #0 /var/www/.../html/nextcloud/lib/private/legacy/app.php(245): require_once()

      #5 {main}","File":"/var/www/.../html/nextcloud/apps/systemtags/appinfo/app.php",
    "Line":64

I have remove all cookies and session data in Firefox.

How can I provide more information (if necessary)?

This looks fishy - as if the request does not load via the index.php but via a different entry point, which then fails. So this looks like a setup issue in the web server IMO.

As this seems to be a setup issue I would like to ask you to raise your question in the forums: https://help.nextcloud.com

@MorrisJobke indeed something went wrong during upgrade. The updater passed all checks. But the disk was almost full and it seems some files got corrupted. After tidy-up, I could not call the upgrade tool to fix the integrity. So, I evilly decreased the version by hand and could re-run the installer. This fixed the issue.
