You can fix this in two different ways:
- Uninstall you current Dokany version and reinstall the latest 1.x version (not the 2.x version). Just follow this post how you do both of it: Error TMN6:3HIN:3SJV · Discussion #2004 · cryptomator/cryptomator · GitHub
- Replace Dokany with FUSE by following WinFSP: How to use it
…then you will have access to your vault again
