lagging/stuttering when the desktop app is in use

Question

Adobe Lightroom Version 8.4 
Apple M3 Pro - MacOS Sequoia 15.5 
Lightroom is lagging/stuttering when the desktop app is in use. It gets hung up on "preporting" when attempting to export, indefinitely. This means I can not edit my photos properly and then I can not export them to be saved. There is a bug that needs to be fixed. As of now I am unable to proceed with my photography because the app is so bugged. (Cloud-based). [moved from bugs to discussions according to the community rules - Mod.]

Hey, @michelle_6995. Welcome to the Lightroom Community. I'll need more info to help you figure this out. Is this a personal or work (IT-managed) machine? Has this started after recent Lightroom or OS updates?

What is the image format of the original files? Does this happen with all the images? Before going further, you must ensure all the data is backed up locally or in the cloud. You can log on to Lightroom Web (https://adobe.ly/3LUKpiM) to check and confirm everything is synced.

Also, is Sync enabled when you are editing in Lightroom? You can click on the cloud icon in the top-right corner to pause the Sync activity.

You can try exporting the images from Lightroom Web & check how they're downloaded.

Let me know how it goes. Thanks!
