also - I updated my Mac to Bug Sur - still getting the same message.. I uninstalled and reinstalled lightroom after Big Sur upgrade, that hasn't resolved the problem either unfortunately.
Also, I tried accessing the log through the Lightroom CC folder, but I couldn't find that folder for some reason - sending below a screen shot of the path that I have incase you may find it handy.
It took a few tries ... we managed to open it on one of the restarts, during the couple of seconds just before the "clean up" message opens and locks everything up. Good luck!
ok so here's what I did - like you said.. when you open lightroom, in the second before you get the pop up, click on the cloud icon to open the sync window.. then VERY quickly hover over the blue syncing circle that says 'syncing photos' - the blue circle icon will change to say 'Pause syncing' - click on it. it should then say "sync Paused". you will then still get the popup warning about cleaning - click OK.
If you did it right (pat yourself on the back for having the fastest fingers in the west!), lightroom will restart, the cloud icon will say syncing paused by default and you won't get the error anymore.
to note - as soon as I switch the syncing in the cloud icon back to "resume syncing", I immediately get the popup window about "cleaning" and get stuck in the continuous restart loop.
I restarted the steps above and paused syncing and it worked fine so no dramas, BUT @Rikk although keeping the syncing paused doesn't bother me much (as I am working locally), it would be great if there is a solution that would allow us to resume syncing and not get the pop up (incase in the future I wanted to save to the cloud).
Thanks @mmakki ... we've done what you suggested, and that has also worked for us, we are finally out of the 'clean up' loop. But we now don't seem to have any of our previous edits in Lightroom. When we try to use Lightroom to open the copy and renamed versions of the Lightroom Catalog, we have nothing there. I can see that there are plenty of folders/subfolders (138MB worth) ... but when we try to open the library via finder, Lightroom opens without any images.
this goes beyond my technical expertise tbh - im not an expert user in lightroom, I use it to edit a few photos now and then... Im guessing @Rikk would be best to help out with this?
@Rikk I'm on Windows 10 and I have this problem. I've never had a problem with any other Adobe products, just this one. I own it through my school and it's not expired yet. I only just got this PC one month ago so there shouldn't be any problem.
I tried uninstalling and reinstalling, same thing happened
hi *weepingangelemma we found a solution, its in the post below... i made another post with clearer instructions here.. fyi it works for mac but dont know if it does for Windows
*Kurt Hopefully you can get back the edits that you previously worked on. I haven't used it yet so in my case, the paused syncing is okay for me. I fortunately have 1TB of space to work with so it's fine that I can't use the cloud.
@Rikk It's fixed for now. I looked at another comment and the paused syncing worked for me although I can no longer use the cloud for any future projects.
@Deleted User I still have the lightroom needs to restart to clean some things up for you and cannot pause the syncing like suggested by @mmakki anythiung else to trY?
