contao calendar (event list) Warning: Undefined array key "languages"

[JessesNei]

PHP 8.1 Contao 4.13.23 CM: v1.32.35

What is the connection between Contao event list and the catalog manager? I create a frontend module of type event list and select an event archive.

When loading the frontend I get (happens if there are events published or not)

ErrorException: Warning: Undefined array key "languages"
