ios app crashing when attaching to debugger

[Shahrukh0396]

Description

i have recently migrated to 0.78 and everything works fine except i can't view any logs on the terminal whenever i try to open the dev tools, the app is crashing some observations are that user_script_sandboxing is enabled in this version but in my migrated project it is disabled and enabling it will return an error that shows that some of the scripts are not working in build phases

Steps to reproduce

migrate from 0.74 to 0.78 and run the ios app

React Native Version

0.78.0

@Shahrukh0396 Can you also add a stacktrace with the crash?
The User Scripting Sandboxing needs to be set to NO, as we need to run some script to set up the Hermes JS engine properly.

WebSocket connection to 'ws://localhost:8081/debugger-proxy?role=debugger&name=Chrome' failed this is the only stack trace i have recorded when opening devTools on ios physical device.
