Android profiling crashes Podcast app on startup #64458
Description
Following the steps outlined in https://github.com/xamarin/xamarin-android/blob/main/Documentation/guides/tracing.md, and running the https://github.com/microsoft/dotnet-podcasts app, I'm seeing the app crash on startup.
Looking into the logcat, I see the following:

Notes
-
I am able to profile a
dotnet new mauiapp just fine. There has to be something special about this app that is causing it to crash. I can share an.apkfile, if someone is interested. -
The
dotnet-podcastsapp is still on Maui 12. I have a branch with it updated to the latest here: microsoft/dotnet-podcasts@main...eerhardt:UpdateToLatestMaui. If someone is trying to reproduce this locally with the latest bits, it would be easiest to start with that branch, and notmainofdotnet-podcasts.
