Lightroom fails after a number of metadata edits
I'm photographing a large wine cellar collection and taking three photos of each bottle. I want to title each photo with the same wine name. I try to do this by selecting the three matched photos, and pasting in the "official" name of the wine into the title, return, and answer yes to the multi photo question. This always works, but, when I move the selection to the next photo and then select it and the next two photos, I eventually have a problem. The cycle goes well at the start, but starts to slow down and after three to ten sets are done, the program seems to get caught in some sort of loop. The focus shifts to my second monitor, back to the photo I'm trying to select, somewhere else, etc,etc. I tried just leaving it run for a couple of hours to let it clear, but to no avail. My only solution is to keep hitting the X in the upper right corner over and over, until it seems to catch Lightroom between steps of its loop. Restarting Lightroom fixes the problem, but starts the cycle count down until it happens again. The problem also shows up when I try to stack the three images, and select another set to stack. In this case, I usually can make it through a higher number before it gets caught in the same loop. In both cases, if I wait after selecting the first new photo, but before selecting the second and third, I increase the time to the program getting caught in its loop. This doesn't seem to prevent it, just seems to allow me to get more sets completed. I'm running an I7 system with 64GB of RAM and with both an NVMe boot drive and an SSD data drive. System performance in all other areas of Lightroom seems to be fine. Any guidance will be appreciated.
