There is a problem from time to time (especially if you are using some VPN) where Docker will hang (not sure about the latest update as of today) but before.
Close Docker Desktop. After that manually kill the Docker process. Go to “Activity Monitor” and search for process “Docker”. Make sure it is one with a blue icon in the first column.
Open Docker Desktop, and run DevKinsta again.
I do believe everything should be good after this.
The problem is with Docker itself on Big Sur I think, not with DevKinsta, as DevKinsta can’t access docker manager to start containers.
