Failed to create WDA session while running iOS automation in simulator

Appium version: v1.21.0
xcode version: 13.0

Everything was working fine for me. Suddenly after updating the Appium, I am seeing this error “Failed to create WDA session (An unknown server-side error occurred while processing the command. Original error: Could not proxy command to the remote server. Original error: connect ECONNREFUSED”. I am using simulator to run my iOS automation. WebDriverAgent installed and then uninstalled from the device. Not able to launch the app.

+1 Even i am facing the same issue with similar configuration
And resolution u got so far?

you can solve it by updating appium to v1.22。see it

We use appium 2.0.0 beta 46 and face same issue, any clue ?)
