I haven an installed Bitwarden on mac. After months of successful usage something happened with the installation. Folders are not displayed, but the values are still present in the database. Folders and values work from web and mobile app. Restart, reinstall don’t help
There was an issue with the prior desktop app, but you can address it by logging out and deleting the data.json file in your appdata folder.
Once cleared it should be good to go!
