Xamarin Forms Android Views Inflate Exception - xamarin

Question

In my forms project, when navigating to the shell page from content page , i am getting Unhandled Exception: Android.Views.InflateException: <Timeout exceeded getting exception details>
. I am using visualstudio 2017 community version.Important thing is there is no error when using visualstudio 2019 community edition.This happened after merging with a sub branch.I have tried deleting bin,obj folders, downgrading xamarin version etc.Nothing found useful.I am stuck at this point.Please help...
