Help!!! Lost All Photo Edits in Lightroom Due to Sync

So, unfortunately, I was mainly using Lightroom CC.  There are a few things I've liked better with Lightroom Classic, and so have gone back and forth between the two, but 90% is done in Lightroom CC.  Somehow, there was a disconnect this time around and while I thought my work had been syncing and saving, it was not.  I exported the photos out of Lightroom Classic when I was done editing, to realize they had not been syncing and therefore were not the edited photos.  When I tried to go back and see what had happened, I somehow synced all my pictures with the settings from one picture.  Of course, it then synced with everything and by the time I realized what was happening and paused it, the damage was done.  I am wondering if the latest version of the pictures was not in Lightroom Classic, is there is any way I can get the edited pictures back?  I know Lightroom Classic has the history panel on the side, but since all my work had been in Lightroom and it for some reason did not sync with Lightroom Classic, I do not see a History section in Lightroom.  I also tried checking the cloud to see if there is a way to get an older version of my pictures from there, but I also could not find a way.

Sorry for my rambling, I hope that makes sense.  I was just hoping there would be an easy undo for the sync issue and I'm starting to think I might be stuck.  Thanks for the help!

Do you have a recent backup of your catalog file, from just before when this mistake happened?

Lightroom Desktop(?) the Cloud Centric REAL Computer program or Lr Mobile that runs on Mobile iOS and Android devices?

If the Lr desktop program (Cloud Centric) why are you using both versions of desktop programs?

Are you sure the history panel does not include another step before the accidental edit? It would normally show as Imported from Lr Mobile or similar.
