Just updated to 2.24.2 from I think I was on 2.24.
Now getting an error opening the iOS Simulator from XDE.
Error in the React Native Packager (XDE Console)
Error installing or running app. Error: Process exited with non-zero code: 1
Simulator is throwing a error… but I wonder if the XDE start parameters have changed.

I am still investigating on my end for my own mistakes, but thought I would note it in case others are seeing the same.
