2021-03-03T12:04:09.307+00:00 I have updated latest Xamarin forms version and updated all the existing packages. Target android API 29 , Still I am getting same issue. While debugging time app is crashing . Same error I am getting. If I open app without debug app is showing white screen itself nothing happening.
Note: If revert back Android X it is working but I am not able to update Xamarin Essential.If you have any idea please send me the steps to resolve the issue
