So i faced the same issue, thought about it might refusing doing this because of an already Docker process is running and blocking from initializing one (even if no docker opened Infront of you).
So, i just opened Task Manager and searched for Docker and found one running, i ended it, re-opened and worked for me.
This might not be the solution for all but instead of uninstalling and re-installing
Nothing working for me …
except:
docker run --name name_db -p 3306:3306 -e MYSQL_ROOT_PASWORD=your_pass -d -it mysql bash
add -it because initialize interactive console
Faced the same issue after updating to 4.27, tried everything mentioned in the post and nothing worked. reverted back to 4.26.1, and everything works as expected.
I did a reinstall of Docker Desktop for Windows, tried to install it with Admin rights, cleaned up config files. Nothing helped on my Windows 11 Pro laptop. I ended up with installing an OLDER VERSION of docker desktop 4.21.1 which seems to be stable. (I disabled the Docker desktop option “Automatic check for updates”) The com.docker.diagnose.exe message disappeared.
