I have installed Windows 10 20H2 version in my system. And Visual Studio Professional 2019 preview. I followed this link for MAUI setup.

I have installed .Net MAUI preview 5. And ensured maui-check. All looks great.

I able to create new project in MAUI and it builds succesfully. But when try to deploy in device, it shows below error.

For me the solution was to add RuntimeIdentifiers as pointed out by @tony

In my .csproj file i added the line with RuntimeIdentifiers as in the following snippet

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
    <RuntimeIdentifiers Condition="$(TargetFramework.Contains('-android'))">android-arm;android-arm64;android-x86;android-x64</RuntimeIdentifiers>
    <TargetFrameworks>net6.0-ios;net6.0-android;net6.0-maccatalyst</TargetFrameworks>

I had the same problem in Release mode, yet the project was successfully deployed in Debug mode. Finally managed to fix the problem as follows.

Set the build configuration as Release, and then right click on project -> Properties -> Android Options -> Advanced (on the bottom of the page)

Under the Supported architectures make sure that the options of x86, x86_64 and arm64-v8a are selected.
