Docker daemon fails to start (windows)

I have a database in a container and everything worked fine so far. But when I tried to use docker today I got this error:

error during connect: This error may indicate that the docker daemon is not running.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version": open //./pipe/docker_engine: The system cannot find the file

I saw some post related to that problem but none of the proposed solutions seem to work in my case. Virtualization and Hyper-V is activated. When I start docker using I can see the little icon which indicated that the docker daemon is running but after 10 or so seconds it just disappears.
I already tried to restart, of course. I think that I maybe have to reinstall. If so, what happens to my containers? Im pretty new to docker as you can tell.
Thanks :slight_smile:
