SIGABRT crash on launch with Mapbox Android SDK bindings — works in .NET 9, broken in .NET 10

[natevarghese]

Android framework version

net10.0-android

Affected platform version

.NET 10.0.203

Description

A .NET Android bindings project that includes the Mapbox Maps SDK AARs crashes immediately on launch with a native SIGABRT in both .NET 10 emulators and real devices. The same setup works correctly in .NET 9.
The crash occurs before any managed code runs — Application.OnCreate is never reached. The same Mapbox SDK version is used in both cases. It looks like the .so files are being loaded twice, or in the wrong order.

What I tried

1. IInitializer / AndroidX Startup — attempted to pre-initialize Mapbox via androidx.startup but crash occurs before any initializer runs.
2. ContentProvider pre-init — implemented a custom ContentProvider with OnCreate to pre-touch Mapbox classes before Application.OnCreate. Crash still occurs before ContentProvider.OnCreate is reached.
3. Disabled all Mapbox InitializationProvider entries — confirmed via merged manifest that all Mapbox AndroidX Startup initializers are removed. Crash persists.
4. Confirmed classes are in DEX — BaseMapboxInitializer and MapboxMapsInitializer are present in classes.dex.
5. Confirmed single libc++_shared.so — no duplicate copies in the APK.
6. Proguard/R8 — already disabled in debug builds, not the cause.
7. Using newest version of the Mapbox SDK.

Steps to Reproduce

Reproduction Repository
https://github.com/natevarghese/DotNetMapbox
A minimal reproduction repository is provided with two separate solutions demonstrating the working (.NET 9) and broken (.NET 10) behavior side by side. I added global.json to each solution.
/
├── Net9/ # Works correctly
└── Net10/ # Crashes on launch

Open each solution independently and install workloads. Run on android emulator or device and observe crash on .Net 10 project only.

Did you find any workaround?

No
