Hi, I have the same problem with nautilus-nextcloud 2.6.4-1.
When I start nautilus from the command line I get this warning: ** (org.gnome.Nautilus:36227): WARNING **: 21:34:08.527: /usr/lib/x86_64-linux-gnu/nautilus/extensions-3.0/libnautilus- python.so: undefined symbol: _PyNautilusInfoProvider_Type Maybe this indicates the root of the problem? Cheers, Björn
