Mac Sonoma/conflicted copies and app isn't loading

I have exactly the same sync problem right after installing Sonoma on a Mac book pro. Conflicting copies of all folders, no files left in the original folders, and after uninstalling the Dropbox app it is impossible to get it to run again, it always crashes on launch.

I tried pretty much everything, restarting the mac, trying on the web app to fix the sync, nothing worked since now.

Waiting here for a solution.

I precise that the group with which I shared the folders and files don't see the new "conflicting copies" of any folder, but they also lose the files in the original folders.

Thanks to anyone who can help to fix the issue.
