await CrossFilePicker.Current.PickFile() not working for pdf files - xamarin

Question

I am using await CrossFilePicker.Current.PickFile() for file picking in xamarin forms but it is not working for pdf files, I am getting the exception below:
Exception :

How can I resolve this?

As Jason said, you could use the Xamarin.Essentials. The code below to pick pdf files for your reference.
async Task<FileResult> PickAndShow(PickOptions options)
{
try
{
var result = await FilePicker.PickAsync(options);
if (result != null)
{
Text = $"File Name: {result.FileName}";
if (result.FileName.EndsWith("pdf", StringComparison.OrdinalIgnoreCase))
{
//do something you want
}
}
return result;
}
catch (Exception ex)
{
// The user canceled or something went wrong
}
return null;
}
