Windows client sync folder cannot be accessed under Linux


Nextcloud version (eg, 20.0.5): 21.0.2
Operating system and version (eg, Ubuntu 20.04): Windows 10 / Manjaro 5.4
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4
PHP version (eg, 7.4): PHP 7.4
Windows client: 3.2.3

The issue you are facing:

I have a Dual-OS Setup currently and I have always used the Windows Sync Client to sync my local data drive (NTFS formatted because of Windows history).
I mounted the data drive in Manjaro and could always access the data until…
I had to reinstall Manjaro due to strange, still unknown reason.

Know I can mount the drive itself, and I can see all folders and files. But the three nextcloud sync folders (from three accounts) cannot be accessed and are shown as unknown for permissions and ownership:
ls -la shows:

d??? ? ? ? ? ? nextcloud

I tried to remove writing protection within windows, but this didn’t help.

Not sure if this is connected to the client or a Windows 10 library issue, or is a problem from the Manjaro installation.

But any hints would be very welcome.

Kind Regards
