Default MAUI Blazor project immediately crashing on Android Emulator

[efonsecab]

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

Hi @efonsecab can you confirm whether a non-Blazor MAUI project works for you?

Hi @Eilon, I have the same problem reported with one setup very similar, in my case i got the same error with non-Blazor MAUI.

Having the same issue the debugger stay attached when running Maui app but when trying to debug a MAUI,Blazor app the debugger will not stay attached to the emulator or device

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

Thank you @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.

The good news is that it no longer appears to be happening with Preview 6. Get Outlook for Android<https://aka.ms/AAb9ysg>
