--- Comment #3 from stephematician@gmail.com --- The issue started for me after upgrading to wine-staging 10.0-rc1, with a clean wineprefix, then I set Z: to /home/username and the issue occurs. If I set Z: to / then the issue does not occur.
I reverted to wine-staging 9.22, started a clean wineprefix, and set Z: to /home/username and did not experience the same issue.
