LRc export not working for large number of photos

[defaultf2xesqb98b5w]

My catalog is  just over 100,000 images and was trying to export large number of select images for archive.

If you select a couple hundred and click export it works as expected.  If you select a few thousand after you click export nothing ever happens(left it for several hours).  Is this a known limitation? I could find no answers online as there is no error message.

Thanks in advance

Hey, @defaultf2xesqb98b5w. Welcome to the Lightroom Classic community. I'll need more info to help you figure this out.

Please share the system info of Lightroom Classic from Help > System info > Copy & paste into a text document > Upload and share with us here.

Where do you keep your Lightroom Catalog & the images? On the internal or external drive?

One of the first things to check is to ensure that none of the images selected are currently missing/unavailable to Lightroom.

Go to Preferences > Performance > Use Graphics Processor > Set it to Off or set it to use for export & test the outcome.

Does the activity monitor show a spike in CPU, GPU, or Disk usage when you click on export?

Let us know how it goes. Thanks!
