Hey, @Louis Boucquet & @benm90715678. Welcome to the Lightroom Community. I'll need more info to help you figure this out. Please share a video showing your development operation, along with an image & the system info from Lightroom: Help > System info > Copy and paste into a text document > Upload and attach here.

Does this happen with a specific set of images? Were these images imported into Lightroom on the same device or via another surface with Lightroom?

Check if export works with Lightroom Web (https://adobe.ly/4exBz9y)

Let me know how it goes.

Thanks!

Happens to any image have processed through the windows version of Lightroom. The images export fine - but cannot handle exporting one sharpened via the new Topaz AI. RAW images were uploaded directly into Lightroom, as always have, edited, then given the new AI sharpen treatment (still within Lightroom) - thus a new DNG is auto generated. It is this DNG which gets stuck.

New Lightroom version - Images that are processed with the new Topaz sharpen tool do not export. The progress toolbar (top left) shows the number of files being in line. But they remain permenantly "in progress". All other images export, even if the Topaze images are still waiting.
