Lightroom Classic alternating between working and "Not Responding"

[photofan1]

I do a lot of sports and event shooting. I exported thousands and thousands of photos from my other photographers from a three-day event, downsizing and watermarking. Then I turned to do the same of my own first day's images, almost 9,000. At the 6.5 hour mark, with the job only 60-70% complete, I finally took a break from dragging the already processed images into different folders,  and went back to Lightroom Classic. It turns out, it had, and is cycling back and forth between exporting images for 2-10 seconds, to "Not Responding" for 4-40 seconds. 

I never noticed because it was always making progress, and I never stayed on the LR window long enough to see it "Not responding" for very long. I've purged the cache, free'd up storage space on laptop SSD (now 228GB of 911 free, while the external SSD the images are on, has 509 GB free on 1.81TB drive). I uninstalled the current version and reinstalled a couple older versions of  LRC. That didn't help. Nothing has helped. I've backed up two of the catalogs that have been used recently. I've optimized the catalogs. I've restored the original preferences. . 

I have an older Windows 10 system with 24GB Ram. MY GPU is old and can't help assist Lightroom. There are no new drivers to update, I don't believe.  I've updated windows once, and restarted multiples times. Any help is greatly appreciated!!

Thanks!!

Also, the Lightroom Window often flashes, or flickers, when it's not responding, or goes back to working. It suddenly appears or disappears or simply flashes as it cycles between the two states.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

I get the following message: Unexpected error performing command: ?:0: attempt to perform arithmetic on a nil value

When the LRC window is not on the front of my display or minimized, if I go down to the task bar and hover over the icon/logo, there are two headlines above two boxes, one that says LR and the other says "shadow". It's like the program has two windows open, but when you click on the "shadow" nothing, not a pop-up window, etc. is there.

From your Sys Info

Built-in memory: 24340.0 MB

Strange amount?? How much RAM does this laptop have?

Laptop, correct?

[GoldingD]

From your Sys Info

Graphics Processor Info:

 nothing listed. So, laptop? Some laptops only have an integrated video card, and no descrete Graphics Processor.

Does your laptop have a GPU? 

So, as you sort of stayed, the LrC option to use GPU will not work on your rig. If somehow on, turn off.

P.S.

Displays: 1) 1920x1080

so, not 4K, no value in use GPU option. Could in fact hurt.

[photofan1]

24GB of Ram. Older laptop with older GPU, it is turned off, can't assist Lightroom. Full HD display, not 4k.

[photofan1]

GPU: Intel(R) HD Graphics 4600 

[GoldingD]

GPU: Intel(R) HD Graphics 4600 

So, checking at:

https://www.notebookcheck.net/Intel-HD-Graphics-4600.86106.0.html

You do have a GPU.

BUT, you have turned it off? As not any help in LrC/

That means, the integrated vudeo card is all that is being used to display in LrC.

Even though LrC will not leverage that GPU (apparently) does not mean it is not helpful at all. Dies LrC get even worse if on? (possible)

More at:

https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

And your reason for turning that GPU off, may be right in solution 1.

[photofan1]

In LrC I have changed the preferances to not use GPU to help accelerate processing, or whatever the extact wording is, because my GPU is not compatible with the last several versions of LrC..
