Entwickeln-Modul öffnet nicht LR 6.14

Do you see the imported images in the Library module under "All Photographs" ("Alle Fotos")?

From there you should open the appropriate image in the Develop module as @dj_paige wrote.

If this isn't work please check the following:

Is Lightroom activated or is it running as a trial version?

Can you open older images in the Develop module?

Try resetting the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com) 

It's recommended to backup your preferences before you reset the preferences to the default settings:

From the translation to English

Previously, the development module always opened after the import.

This is not correct. After Import, the Library Module always appears showing the "Previous Import" collection under Catalog. From there, if you want to Develop your photos, press D. Or you can go to "All Photographs" or any collection or folder and press D.

Develop module does not open LR 6.14

Hello, I ask for support: I am working with LR 6.14. My problem: Images that I import from the hard drive into Lightroom are not displayed in the Develop module afterwards. When I try again, the images are shown as already imported (greyed out, no longer importable).

Previously, the development module always opened after the import. What can I do?

Thank you very much for help!

The title of your post says that the Develop module does not open, but then you say images aren't displayed in Develop.

So does the Develop module open or not?

If it does, can't you see any images at all, or is it just this import?

Please post a screenshot of the entire Lightroom window with an image open in Develop that is not displaying.

There is no need to create a Word document, just post the screenshot itself.
