runtime: [regression/8.0.0-preview.7.8842] - AndroidMessageHandler - Cannot access a disposed object

Description

When running a http client in a second project inside a solution the connection to the web is broken sporadically in the latest .net8 preview. Each request will run into the same error. Restarting the debug session in the emulator can either solve the issue for the entire time the app runs or will still be borked. After several restarts i’ll work again. In .net7 this worked exactly as intended.

Steps to Reproduce

1. Create a sample project
2. Add a second project
3. add an http client to the second c# project (non-maui)
4. call the method from MAUI app with an Android device
5. restart several times to provoke this error
