cannot launch docker desktop for mac

I had the same issue on my Mac. It was working well, suddenly, one day it stops working. After searching a lot, I was able to run it again by the following method:

1. Go to finder and open Applications > Utilities > Activity Monitor.app

2. Find Docker or Docker Desktop (it was in Not responding mode in my case) and Force Kill the app.

3. Run the following command in Terminal:

   sudo rm -rf ~/Library/Containers/com.docker.*

4. Open the setting file in the terminal:

   sudo nano ~/Library/Group\ Containers/group.com.docker/settings.json

then find "filesharingDirectories":

5. Remove all entries inside this key and leave it as "filesharingDirectories": [], save and close the file.
6. Finally go to the Application folder, find Docker and run it (wait sometime, it takes a minute or so to run)
7. It will run and work like a charm!
