Breaking: #87081 - Language update (scheduler) task doesn't work after upgrading to TYPO3 >= v9.2¶
See Issue #87081
The language update command was moved away from ext:lang and was rewritten as a Symfony Console Commmand. https://docs.typo3.org/typo3cms/extensions/core/latest/Changelog/9.2/Breaking-84131-RemovedClassesOfLanguageExtension.html
Running or editing this task is not possible anymore.
An installation is affected if a language update scheduler task was created and exists before an upgrade to TYPO3 >= 9.2.
Delete all existing language update tasks within the scheduler or remove the corresponding record in the database directly. Create a new scheduler task with selected class "Execute console commands" and select schedulable command "language:update".
