After performing 50 to 60 HDR operations Lightroom stops responding. LR slows as more HDR operations are done and then just stops responding. Doing HDR, 3 images each, on dng files, Windows 10, 64g of memory, no other programs running, LR 9.3. CPU usage is about 30% lots of free memory.

What are the file sizes of the 3 images that you are combining with HDR? Have you tried emptying your cache in the Preferences > Performance tab? What is your Camera Raw Cache settings set at? What happens if you bump that up?
Cache size is set to 25G, I have not tried purging. Thanks for the tip!
Files are DJI dng from Mavic 2 Pro, ~ 39MB each. The camera is 20 MB sensor, and I have not figured out why the file size is so large. The image size as reported from LR is 5464 x 3640. On previous versions of DJI drone cameras the file size had always matched that of the camera sensor specification.
I have also experience the same LR symptoms slowing when processing Canon CR2 images as HDR!
I have been processing more HDR images and-
1 - I am in the Library module, not sure of previous times.
2- I have been less agressive of keeping the "tasks", queue, full. Peviously I was keeping 3 - 4 in the queue, this time just one or two and as a result I am not experiencing the same type of slow down that I have multiple times in the past. I suspect there is a memory fragmentation problem of the queue.
