Appium (and desktop) unable to launch wda session since xCode13 and iOS15 - selenium-webdriver

Question

Since my xCode got (automatically...) updated to 13 and all my simulators moved from iOS 14.5 to 15. with the same setup / commands I'm unable to launch the WDA from both the desktop app, and the node ( selenium server grid/node setup)
The issue exists for all simulators.
I can still use real device..
(the actual ports in errors might differ, the first one is from the actual automation where it fails, the 2nd and 3rd is from the desktop app -where it still fails with the same error. the root issue is still the same on both)
The error logs I get:
In short:

Answer 1

To solve this issue,
We need to update our appkum on the computer ( should be 1.22.0 or above)
To see your version:
appium -v
To install / Update your appium:
npm install -g appium
This fixed the simulator part. to fix the appium desktop, you also have to update the desktop app, but now it's moved on as 2 separate app.
One for the server
https://github.com/appium/appium-desktop/releases/
And one for the inspector https://github.com/appium/appium-inspector/releases

Answer 2

I had a similar problem with the old appium (where the server and the inspector were combined), and with the new version, where they were taken out separately.
I solved it by adding server Capabilities:
serverCapabilities.setCapability("wdaStartupRetries", "4");
serverCapabilities.setCapability("iosInstallPause","8000" );
serverCapabilities.setCapability("wdaStartupRetryInterval", "20000");
after that, the wda session became stable

Answer 3

I had the same problem
I solved it by adding appium desired capabilities and I reduced the time from 120 to 60 for newCommandTimeout capabilities
my appium capabilities' last status
"newCommandTimeout": 60,
"wdaStartupRetries": 3,
"wdaStartupRetryInterval": 20000
