There is a Dokany v1.3 bug that floods Windows Logs by generating some mount event every single second.
This bug has been fixed, but no release past that date has been shipped yet. Any chance you could provide a version of cppcryptfs built against one of Dokany's latest pre-released builds (they have a continuous build process so anyone using your build could easily download the relevant Dokany version as well)
I was able to follow your build instructions to make cppcryptfs.exe in such a way and no longer have this Windows Logs flood, but maybe it might be worth it if you made an intermediate release before the new Dokany is released with a fix
