org.cryptomator.ui.model.Volume$VolumeException: Unable to mount Filesystem upon macOS mojave upgrade



I created vault using 1.4.0 sometime end of the last year. recently, i verified with 1.4.9 and works fine 1month back.
Yesterday, i updated OS to Mojave 10.14.4 and updated OSXfuse to 3.9.0
Now, i am not able to open my encrypted storage from cryptomator 1.4.0, 1.4.9 and 1.4.10 apps.

Please help me, below is the log:

Figured it out :hushed:

Cryptomator gives outer error that “not mounting file system”… inner error is osxfuse kext is unable to load…
Somehow, when virtualbox kext loaded, osxfuse kext is not loading…

Unload virtualbox

Unload virual box kext using below script, need to run shell commands with sudo permission.
Just save contents to a file and save as bash script file(extension .sh). Run script file with sudo

for id in VBoxNetAdp VBoxNetFlt VBoxUSB VBoxDrv; do
    kextunload -b "org.virtualbox.kext.$id"

Load osxfuse

sudo kextutil /Library/StagedExtensions/Library/Filesystems/osxfuse.fs/Contents/Extensions/10.14/osxfuse.kext

Run cryptomator as usual…
