Loqseq Desktop will not open mounted local file with full read write permissions

I have setup a Nextcloud Webdev folder mounted and bookmarked in Nautilus.
I can copy paste delete it has ful permissions.
I have copied over all the folder but LogSeq will not open folder or import files.

See video

copy the graph into a local folder. Can you open it in logseq?

that version of logseq are you using and how did you install it? for example: linux, flatpak
