Oh This is on Mac13, I already updated my mac to 14. @hellohuanlin Do you have your mac still on 13?

[cyanglaz]

'/Volumes/Work/s/w/ir/cache/osx_sdk/xcode_14e300c_runtime_ios-16-4_14e300c_ios-16-2_14c18/XCode.app' This is the xcode version.

[hellohuanlin]

Yep im still on 13. i can take a look when get time

[cyanglaz]

I think the test hit this bug: #126627
Which I have created a seperate bug to track the engine fix: #125913

[cyanglaz]

Potential engine fix: flutter/engine#41708
