OS: Mac OSX 13.7.8
Nextcloud Client Version: 33.x (QT6)
After the Nextcloud Client updated automagically, the app didn’t work anymore.
After using the CLI to debug the Problem an error occurs
QT6 QLocalServer::listen: Unknown error
So QT6 cannot create a Listening Socket in the $TMPDIR.
I can delete, create do things in the $TMPDIR, but the app cannot create a QT6 listening socket !
Anyone having the same issue ?
I switched back to the last version which works well. (Nextcloud-4.0.8)
