Hi, I just updated XF to 188.8.131.52
Once in a while when calling ModernHttp component, this bug occurred. Meanwhile if it was built with Cycle 7 Visual Studio then this bug never occur. Only happens on android.
Please help me look into this as I cannot update the app with this bug to my stable releases.
Thank you in advance for the support.

Hello, thank you for filing this report. To help us investigate this issue, could you please include a minimized runnable test case demonstrating the crash? It would also be great to get your full version information from https://developer.xamarin.com/guides/cross-platform/troubleshooting/questions/version-logs/#version-information.
I have the same issue.
Generally it happens shortly after ModerHttpClient can't make a call due to absence of internet connection
