While running my react native app in debug mode, the app will periodically freeze up or if there is a breaking error the app will freeze.
reload with Metro will not resolve the issue. I end up stopping metro and Xcode and restarting. This is getting tiresome to deal with so I am hoping I can find out what is causing the issue.
I am running a React Native App in Xcode 14.0 and using Flipper 0.164.0 (50.0.0) for debugging.
Active Plugins: hermes Debugger(RN), Logs, Network, Redux Debugger, React DevTools
When the App freezes on the IPad I can see the following errors. These don't necessarily happen at the time of the app freezing.
In Flipper I get the following Error:
Failed while retrieving marketplace plugins SyntaxError: Unexpected token < in JSON at position 0
[conn] Disconnected: SalesTrak on <device id>.
app: "SalesTrak"
os: "iOS"
device: "Michael’s iPad"
device_id: "<device id>"
sdk_version: 4
medium: "FS_ACCESS"
rsocket: undefined
I found a way to debug flipper in Chrome. Found the rest of error message. Still not that useful to me yet.

In Xcode, in the logs I also found this Error that appears to coincide with the time that the app freezes.
