Description

### Description

I have an application that only communicates via Bluetooth with an external chip. In debug mode (I use Rider) it works normally, but when I upload it using Transporter and test it through TestFlight, it crashes right at the SplashScreen. The only error log is:

```
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: SIGNAL 6 Abort trap: 6
Terminating Process: TApp [28764]
```

I removed the entire library I use from Plugin.BLE, removed services, and tried a clean initialization, and the same error still persists. Below I’ll include all the initialization code;

csproj:

```

Research direction

Start by comparing the Release and Debug settings in the supplied .csproj, then inspect MauiProgram.cs, App.cs, and App.xaml in a minimal new MAUI project. Reproduce the TestFlight launch crash and collect a diagnostic crash log beyond the SIGABRT entry; done means identifying the Release-only cause and confirming that the app launches through TestFlight.
