Error when unlocking: "Did not find feasible mount point."

Hello community!
When i try to open my vault …
i see this error:

org.cryptomator.common.vaults.Volume$VolumeException: Did not find feasible mount point.
	at org.cryptomator.common.vaults.FuseVolume.chooseNonExistingTemporaryMountPoint(
	at org.cryptomator.common.vaults.FuseVolume.prepareTemporaryMountPoint(

somebody know the correct steps to fix this,

This is a known issue if Cryptomator is unable to quit properly with opened vaults, see

The fix is to delete all the temporary and empty directories in ~/.local/share/Cryptomator/mnt/.
