Can you restart your computer, and then try to launch Devkinsta and check if the issue persists. If it does, trying disabling the “Auto-detect open ports” in DevKinsta >> Settings page and set the PORT to port 80 and 443 respectively as shown in the screenshot.
I am sorry to see that this new DK0005 error is now occurring when you attempt to start DevKinsta. Would it be possible to please share an updated copy of the main.log file with us? This should contain more information about the cause of the DK0005 error and will help us in investigating the issue.
If you can still launch the Docker Desktop app, it may be easier to delete all the Kinsta containers, images, and volumes. Once all data is removed, you can relaunch DevKinsta, which should automatically recreate the DevKinsta containers.
Please note that deleting the containers, images, and volumes will result in the loss of any existing data on your DevKinsta app. However, this process should allow you to start fresh to either pull your Kinsta staging site back to your DevKinsta or import the site using the backup option.
