Attaching Debug from Chrome kills app on iOS

NS 8.0.7
Xcode 12.4

Every time I run ns debug ios the app compiles fine and runs on the simulator.

If I open Chrome to start the debugging process with devtools://devtools/bundled/inspector.html?ws=localhost:41000 it immediately crashes the app.

Eventually after 4 or 5 times of restarting the app on the simulator the debug will connect. Error is

(Asterix added to hide Bundle ID)

I've removed the platforms folder and rebuilt but the problem persists.

ns doctor shows

✔ Component @nativescript/core has 8.0.7 version and is up to date.
✔ Component @nativescript/ios has 8.0.0 version and is up to date.

Is this correct.

Empieza reproduciendo el fallo con ns debug ios en el simulador de iOS; después conecta Chrome usando la URL de devtools indicada y compara los registros de cierre del socket. Una corrección debería dejar la aplicación en ejecución y permitir que el depurador se conecte de forma fiable; verifícalo con las versiones indicadas de NativeScript, iOS y Xcode.
