Problem¶

1. Adding a new recurring scheduler task without end date fails (an end date is always needed) → This is already fixed by #99175
2. An end date is added automatically!! if saving of a new scheduler task fails due to validation errors
   • existing scheduler tasks are not affected

• Could not find the cause in reasonable time.
• Fails with PHP 8.1 and PHP 8.2
• Could not reproduce in latest stable 11.5 TYPO3 release
