HTTP ERROR 500 after update to nc 13

I am also getting an 500 error after upgrade from nc 13.0.0 to 13.0.1
I cannot use the Nextcloud UI anymore. I do get the login page when in Private browsing mode but after login it fails with an error message at the url: /apps/files/

Note that the Desktop client and the Android app can normally connect.
In The Server log I can find:

I cannot use occ (shell) commands since I am on Shared hosting.

Had same problem going from NC 12.0.6 to 13.0.2, did the terminal console upgrade suggestion from server install folder and worked like a champ. Wish developers were more careful on this, but heck, this is what we expect for with open source slight_smile:

Same problem (internal server error) after upgrade from 13.0.1 to 13.0.2.
Unable to access web interface.
Disabling files_versions (1.6.0) with “sudo -u www-data php occ app:disable files_versions” resolves error 500.
After “Error: This app can not be enabled because it makes the server unstable”

The initial issue was solved, so I close this issue. If you get the same error message, the reason is probably different. If there are unwanted interferenced during updates with certain apps, don’t hesitate to open a bug report on https://github.com/nextcloud/server/issues.
