I'm having some trouble with the new Xamarin.Forms update, with version
The app starts normally, but when I try to open any page that contains a sfDataGrid control, the TypeLoadException gets thrown with the following description:

FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Parent class vtable failed to initialize, due to: VTable setup of type Syncfusion.SfDataGrid.XForms.ExtScrollViewer failed assembly:/storage/emulated/0/Android/data/com.mycompany.myApp/files/.__override__/Syncfusion.SfDataGrid.XForms.dll type:ExtScrollViewer member:(null)
02-07 17:47:13.658 E/mono-rt (27527):   at myApp.MyPage.InitializeComponent () [0x00177] in C:\...\obj\Debug

The app runs fine with Xamarin.Forms version, or with the updated version in UWP. 
So far the problem only occurs in iOS and Android, with updated Xamarin.Forms 3.5

How can I solve this problem?
Thank you.

Hi Carlos, 
We regret for the inconvenience caused. 
We can able to replicate the reported crashing issue with DataGrid in Xamarin.Forms. The issue occurs only when the project Xamarin.Forms update version above 3.5 and it is not occurring the previous updates. We have already considered and working on the support of .Net standard support for the update 3.1 in our upcoming Volume 1 release.  
We have already found this issue and logged issue report for the same. We will fix this issue with high priority and include the issue fix in our upcoming weekly NuGet release update and it will be available by February 19, 2019. We appreciate your patience and please use the earlier Xamarin.Forms updates until then.  
You can now track the status of this issue and contact us for any further inquiries through this link,
