Open Debugger in iOS simulator not working in RN 0.70.0

Description

I started the basic AwesomeProject from the getting started in the docs and found that the Open Debugger is not working. Actually, I am unable to debug in multiple ways (safari, standalone devtools, launch.json from React Native Tools in vscode). Is this a known issue? It was working with 0.69:

Version

0.70.0

Steps to reproduce

In terminal run: npx react-native init AwesomeProject

In terminal run: npx react-native start

In vscode run: npx react-native run-ios

Once ios simulator(iPhone 13, ios 15.5) opens do CMD + D on the simulator to open the menu.

Click Open Debugger

Got the same error after I just created a new project. Setting :hermes_enabled => false resolves the problem. I disabled Flipper as well, not sure if that had any effect.

Same issue on RN 0.70.0. Confirm that RN 0.69.0 works fine.

I just switched to expo…
