Lightroom Classic crashes every 10 seconds after startup - Sync issue

[RJEphoto]

Upgraded to the latest version of LR-Classic 4 days ago, no issues. OS/x 12.6.5. 2021 intel-based macbook pro.

The last thing I did before this issue began was add two more folders to my lightroom-sync folders list, previously i had just one folder in there that sync'd to CC no problem. Forums say this issue has been around for 6+ years, are there any solutions aside from "don't use sync"?  I can keep LR-classic open and working longer, sometime if i start it up with my internet connection disabled, but it's not really useable and always crashes now. I got rid of all my sync folders, issue persists.

Tried these steps without any positive result:  manually deleted photos from LR-CC on macbook and mobile device, deleted all sync data from lightroom.adobe.com / account info / delete lightroom library (now contains 0 images/folders across all devices), held down option-key in the LR-classic preferences sync config window to rebuild the sync library, and got it to begin generating a sync debugging report, but it crashes once the app has been open for 10 seconds no matter what. Tried every other option to delete the sync cache. Reset Macbook's NVRAM / PRAM / SMC. Emptied trash. Still crashes every 10 seconds. There is 760mb of data that is in my LR cloud, but 0 images and 0 folders; I can't view what is taking up that space. I can't find anything else in. LR-classic to delete or clear or disable pertaining to image sync.  I've got half a dozen client photo uploads due and my primary work software crashes every 10 seconds. Help appreciated.

Further troubleshooting with positive result at end: 
-found and purged 760mb of images/files directly from the creative cloud app (never directy uploaded to this before)
-logged out of lightroom classic, logged out of lightroom cc on all devices, logged out of creative cloud
-shut down computer, NVRAM/PRAM/SMC reset, -logged back into apps, LR-classic still crashes every 10 seconds, and it's been over 1 hour since purging all of the data from the LR-sync via the lightroom.adobe.com interface.

-Rolled back from latest version to previous (13.0), still crashes every 10 seconds.

-Upgraded to latest version, still crashes.

-Backed up catalogs and uninstalled LR-classic, rebooted, reinstalled 13.0, still crashes
-Removed catalog file “LR5catalog-v13 Sync.lrdata”, still crashes
-REmoved all catalog files from the LR-classic working directory, started Lightroom, started a new catalog,  it remains stable. Switching back to the previous catalog still results in instant crashing, so the problem  catalog level or a corrupt image
-LR stable with new catalog, imported everything from previous catalog into new catalog, stable, re-adjusted general settings, found missing folders, LR was running background processes to update the catalog hierarchy… and then it crashed. Attempted to restart LR-classic after crash and it just hung on the splash screen, spinning pinwheel, force quit, and restarted.  I was finally able to trace down the crashing to the last image I was editing when the original crash occurred; ultimately deleting this image from the disk and catalog has resolved the crashing as far as I can tell. The last edit contained a few basic adjustments, a radial gradient for exposure, and another radial gradient with the new point-color feature in use. Maybe something to do with the point-color tool?

Definitely the point color tool, once it is used on an image that catalog is no longer functional.  Mine does the same thing.  Thanks for the heads up on deleting the individual image! (Point color tool does work correctly in PS-RAW though)

Absolutely Point Color.. I'm sick of these half baked updates that completely mangle a workflow. If this was beta I would understand but to be awake at 1:30am dealing with this with my project 1/4 done is infuriating. I have been dealing with this issue for a couple days now and have come to realize that anytime this issue arises, I just finished using the point color tool. Found this post bc I googled "point color crashes lightroom classic". Hopefully we get a fix sooner rather than later because it is a very useful feature I was estatic to use and all it has done is make me angry for like 3 or 4 days now.
