Hey I had the same issue. Updated and can no longer share drives on Windows.
It appears according to the docs it network share doesn’t work when mounted as a [WinFSP Local Drive]. Volume Type — Cryptomator 1.7.0 documentation see the note there.
The workaround is to mount it as a directory/folder then share that folder. So you mount it in “D:\MyShareFolder” and then you share "D:" so you can access your share folder over the network.
The only problem is when accessing the share folder over the network, it isn’t able to open some directories for some reason. I can’t pin it down on why but any folder name that is too long or has spaces then it will fail to open. It fails to open files too.
Kind of annoying.
