Default MAUI Blazor project immediately crashing on Android Emulator

Describe the bug

I recently setup another development environment to work with MAUI Blazor, however, when I try to run the default app in the Android Emulator, it opens but immediately crashes, and the debugger window shows the following lines:

[.MAUIBlazorDem] * Assertion at /__w/1/s/src/mono/mono/mini/debugger-agent.c:4389, condition tls’ not met Thread started: dotnet/aspnetcore#5 [libc] Fatal signal 6 (SIGABRT), code -6 (SI_TKILL) in tid 13003 (ThreadPoolForeg), pid 12934 (.MAUIBlazorDemo)`

To Reproduce

1. Setup MAUI Environment
2. Create a new MAUI Blazor projet using the default template
3. Create an Android Device for API 30.
4. Run the project using the created device.

Exceptions (if any)

No visible exceptions in the emulator, app just closes.

Further technical details

• ASP.NET Core version: 6
• Include the output of dotnet --info
• The IDE (VS / VS Code/ VS4Mac) you’re running on, and its version: Version 16.11.0 Preview 2.0
• Host OS: Windows 11

The good news is that it no longer appears to be happening with Preview 6.

Thank you @PaulSorauer-IPGhttps://github.com/PaulSorauer-IPG this does look the same. I’ll let the Android experts have a look and they can close if they confirm it’s a dup.

Got it. It doesn’t sound to me that this is Blazor specific, but perhaps a more general issue with debugging and Android.

Yes… There’s already an issue for this: #1361
