Description

Using the new MAUI app template, adding a webview component and set Source to https://google.com .

On Android, request timeout after a few minutes. This used to work fine on Android a few months ago. Other platforms still work fine.

Worth noting that even if the Source property is removed, the strange errors in the log still happen.

Steps to Reproduce

Use Windows 11 with Visual Studio 2022, latest version as of 2023-04-11

Create brand new .NET Maui App

Add WebView component to main page

Set Source property of the web view to https://google.com

Run application in Android emulator or device. Notice nothing happens. Notice a timeout error is displayed after a few minutes.

Note that Android works fine when run from MAC and VS for MAC. Issue is only on Windows with Visual Studio.

Version with bug

8.0 (current) and .NET 7 newer version after January

Last version that worked well

6.0.424, older .NET 7 version from January

Affected platforms

Android

Affected platform versions

All Android versions

Did you find any workaround?

No. Only rolling back to an old .NET 7 version works, or .NET 6.

Relevant log output

Endless loop of this strange error...

I cloned the app and it ran just fine on my Android Emulator on Win11. I tried running with and without debugger, everything was fine.

          Hi @jjxtra. We have added the "s/needs-info" label to this issue, which indicates that we have an open question for you before we can take further action. This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.
          Rebooted computer and I can deploy to emulator and it works fine. On device, when deploying debug build app crashes on launch. In release mode it works fine on device. So things are at least in a better state. I guess we can close this issue. Not sure why debug build crashes on device (definitely not the first time this has happened in debug) but I can at least move on with release builds for now.
Why things got into a bad state I am not sure. But the log that I posted above no longer cycles endlessly with the parcel error and the browser is working.
