Description

I am using Debian Buster as Host, and Windows 10 (1810) as Guest. When I save the Guest and restart it several times, I get the above error. Sometimes before, after restore, I could see my Shared Folders in several instances, although none of them worked. I had to delete the Shared Folders in the GUI, and to recreate them to get them work.
It seems to be that saving and restarting the Windows Guest replicates the Shared Folders, making them unusable.
Now, deleting the Shared Folders does not help (ticket #6314). I have attached the vbox.log, and an extract of the snapshot file (better: save state file), which includes 35 instances of the Shared Folders. I have tried all combinations of Shared Folders (permanent, automount) When I do not save and restart the Windows Guest, but shutdown and start up Windows, I have not observed this effect - but it takes much more time...
