Metadaten können nicht geschrieben werden, weil angeblich keine Fotos dazu gefunden werden

Hi @BerndS59, I'm just checking in to see if the suggestion helped or if you are still running into this issue? Let us know how things are going. Happy to keep troubleshooting with you if needed. Thanks! ^CH

Hi @BerndS59! Thank you for reaching out! I'm sorry to hear about your issue. 

You might find this post by richardplondon helpful — it explains why writing metadata externally can sometimes fail: https://adobe.ly/4mbg3sr

You can try out these fixes below, see if they work:

1) In the Library module, please check if there's a ? Icon on the thumbnails. If so, please check this page for steps: How to find missing images and folders in Lightroom Classic

2) If the folder or image files are set to read-only, Lightroom can't write metadata. Right-click the folder/Files in Windows Explorer> Properties> Uncheck Read-only.

3) Try optimizing the Catalog via File> Optimize Catalog. If that doesn't help, could you test with a new catalog?

Could you please share some of the files that were affected by this? You can share via Google Drive, WeTransfer, or another public file-sharing platform with your response.

Let us know how it goes! 

Cheers!
