Docker for Mac beta 34+ added extra integrity checks for the qcow2 file on VM start. Your logs contain the error
block device raised exception: (Failure "Found two references to cluster 139760: 118254.39256 and 84.43344")
Unfortunately this means that -- sometime in the past -- two groups of sectors in the virtual disk have become mapped to the same physical sector. It's unsafe to write to the file in this state. Unfortunately the only option is to use "Whale menu" -> "Preferences..." -> "Reset" -> "Reset to factory defaults". Unfortunately your containers and images will need to be rebuilt.
I suspect this may have happened when we enabled "online compaction" feature to reclaim space in the qcow2 file. The online feature is now disabled so I believe the problem should be fixed.
I apologies for the inconvenience. By the way beta 34 hotfix 1 was just released -- it has a bug fix relating to importing containers from toolbox. I recommend running the hotfix if you plan to import from toolbox.
