Mac Os 15.7
After updated to 33.0.3 nextcloud would start and show files to be synced status “0 of 177mb to be synced” and later “syncing changes” but nothing happenend.
Downgrade to 33.0.2, 33.0.1, 33.0.0 didnt help. Neither did upgrade of the OS to 26.4.1.
What resolved the issue was to close the nextcloud client (also the processes in the activity center) and to delete the .db file in the nextcloud folder and restart nextcloud. This rebuild the database, synced a couple of files. Everything seems to work fine now.
I am posting this as I could find thread for my issue. Maybe I can safe someone else hours of search with this thread.
Thanks.
