"The directory /run/user/.../Logseq has been renamed or deleted"

Now and again I get this error, I'm not sure what causes it but I suspect it's a system or flatpak update:

> The directory /run/user/1000/doc/87e1dc54/Logseq has been renamed or deleted, the editor will be disabled for this graph, you can unlink the graph.

As I understand it, this directory is a sort of virtual directory pointing to the location I give the app when opening a graph as a local directory. In this case, the folder is empty. The path with ID `d6417513` _does_ have my graph, but Logseq doesn't know to look there until I open the graph again as a local directory.

I didn't see any issues raised with this problem so I wonder if it's an uncommon problem caused by something I'm doing. The only thing I can think of is that I have my journal on a second drive. Here is the `fstab` entry for it:
