Current patches don't work for me. Using Drupal 11 with content moderation, content translations, scheduler 2.2.1 and scheduler_content_moderation_integration 3.0.4.
What was initially described is still happening.
Patch from comment https://www.drupal.org/project/drupal/issues/3356667#comment-15753938 🐛 Error: Cannot read properties of undefined (reading 'settings') with dialog.position.js Needs work doesn't work for me on D10.2.8. Error is still there.
Unfortunately, patch number 30 doesn't work for me. There is one small mistake which causes on each save to delete the date from the fields. I have changed $element['value']['#custom_format'] ?? $format to $element['value']['#custom_format'] ?: $format as the #custom_format is actually empty string by default.
