docker-machine-parallels: Docker Machine is not running properly after update to macOS Catalina

After the first generation of a new machine (in my case done by “dinghy”, a reverse proxy solution) everything seems to work normal. But after stopping the machine and try to start it again, its not working anymore. The startup ends up with this error message

Unable to verify the Docker daemon is listening: Maximum number of retries (10) exceeded

After starting the machine with debug option I get ten times this fault, before the upper error comes up again:

Watching the bootup sequence by opening the miniature window inside the parallel controll panel I see several errors and warning during the first bootup:

...
unable to write 'random state'
...
unable to write 'random state'
...
Device "eth1" does not exists.
...
unable to write 'random state'
...
unable to write 'random state'

Independent of this messages the machine works as expected until I stop and start it again. If I doing this, I see only one warning during the bootup inside the parallels window:

warning: unable to find partition with the swap label (boot2dockerswap) or TYPE=swap (so Docker will likely complain about swap)
- this could also mean TCL already mounted it! (see 'free' or '/proc/swaps')

I have two macs (both already updated to macOS Catalina) with exact the same problem (after updating the system).

There is also an issue I posted at the dinghy repo, but the autor means the problem stuck inside docker-machine or this parallels connector: https://github.com/codekitchen/dinghy/issues/290
