I have tested the given solution but still getting the same exception.

await MainThread.InvokeAsync(async () =>
{
    fileResult = await FilePicker.PickAsync();
});

I have updated Xamarin.Essentials to 1.8.0 and also mentioned all permissions in the Android manifest.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:requestLegacyExternalStorage="true" android:versionName="x.x.x" package="com.xxxx.xxx" android:installLocation="auto" android:versionCode="xx">
	<uses-sdk android:minSdkVersion="28" android:targetSdkVersion="33" />
	<application android:allowBackup="false" android:theme="@style/MainTheme" android:icon="@drawable/AppIcon" android:label="xxxx"></application>
	<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
	<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

For Android 33, I have implemented Android Native code to pick and read the file, it's working fine for me.

You managed the NuGet package and updated Xamarin.Essentials for your Xamarin.Forms and Xamarin.Android project, right? You could try cleaning the bin/obj file and uninstalling the app from the device then debugging again.

Hello,

First of all, please check whether the permissions are missing or not.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
<!-- Required only if your app needs to access images or photos that other apps created -->

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />

<!-- Required only if your app needs to access videos that other apps created -->

<uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />

<!-- Required only if your app needs to access audio files that other apps created -->

<uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />

Then please make sure you've updated Essentials to version 1.7.5 or later. I can reproduce the issue with Essentials 1.7.0 even though I set the permissions.

For more details, please refer to File picker - .NET MAUI | Microsoft Learn.

(Currently, Xamarin.Essentials is a part of MAUI, and this doc is about MAUI.

Xamarin.Essentials: File Picker doc doesn't point out permission issue, please see the similar issue at GitHub- [Bug] Storage permissions Android 13 api 33 · Issue #2041)
