לא מצליחה לייצא תמונות בפורמט jpeg

Hi,
Thanks for reaching out. We are sorry about the trouble with Lightroom’s export. We are here to help!

Could you please share the exact version of Lightroom (Help> About Lightroom) along with the version of the operating system you are working on? Does this happen with any specific album of images, or are all photos exporting only .DNG file?

Please check here to reconfirm the steps you are following to export images using Lightroom Classic or Adobe Lightroom Desktop.

Adobe Lightroom (macOS/Windows/iOS/Android) - https://helpx.adobe.com/lightroom-cc/how-to/export-share-photos.html

Adobe Lightroom Classic (macOS/Windows) - https://helpx.adobe.com/lightroom-classic/help/exporting-photos-basic-workflow.html

Please let us know if this helps you out!

Thanks!
Sameer K.
