Photos not appearing in folders on Mac after exporting through Lightroom Classic

Hi all!

I am an experienced Lightroom Classic user on Mac, but for the past several months something strange has started happening. After editing my photos and exporting them (usually to low res and high res jpgs in new folders), often the whole newly created folder does not appear where it should be and the images are not visible. For example, selecting to export a batch of images to a new folder directly on the desktop, the task will be completed but no folder will appear on the desktop.

The problem is not accidentally exporting to a different folder. The folder or images simply do not appear.

When searching for the image or folder name in Finder, it finds it, and shows the correct image in the correct folder where its meant to be (inside the Finder search window). But only sometimes does clicking on the image/folder in Finder make it appear where only moments ago it was invisible. If I try to re-export the same images to the same folder, despite not showing up, the programme will tell me the images are already there.

This problem is pretty much always fixed by a computer restart. The folder and images will suddenly appear where they were meant to be. However this is annoying to be happening most of the time and constantly rebooting the computer disrupts my workflow. Can it be my computer running low on juice? I am working on a a late 2015, 27" iMac with 24gb memory and there is still nearly 500gb of storage available.

Thanks for any help!
