We discussed the issue on GitHub: https://github.com/cryptomator/cryptomator/issues/908
And came to the conclusion that the new Dokany version isn’t as backwards-compatible as we’ve thought.
Here is the new installer with an older Dokany version: https://dl.bintray.com/cryptomator/cryptomator/1.4.11/Cryptomator-1.4.11%2B114-x64.exe
Does that work for you?
