Hide local "Nextcloud" sync folder, Desktop client

Nextcloud version (eg, 20.0.5): 27.1.0.7
Operating system and version (eg, Ubuntu 20.04): Debian 12.2.0-14
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.57 (Debian)
PHP version (eg, 7.4): 8.2.10

The issue you are facing:
I use local “.Nextcloud” folder as source to be synched to the server. I configured it hidden (leading dot) for not being listed by default. Two subfolders of my home like “Documents” and “Images” are moved there and symlinked to my “/home” to be used as usual and no need for “.Nextcloud” to show up on folders list of my “/home”. This is working as expected for starting but some hours later stops for unknown reason throwing a message like “configuration not valid” in the clients settings GUI.
May be a bug?

Is this the first time you’ve seen this error? (Y/N): ‘Y’

Steps to replicate it:

  1. Se issue above

The output of your Nextcloud log in Admin > Logging:

Just enabled client logging. No items yet

thx

Last time this happened i restarted the client. Did not happen anymore since then.
