Description

Cannot launch & connect to browser when used in native AOT app.

Complete minimal example reproducing the issue

<!-- PuppeteerSharpRepro.csproj -->
<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <PublishAoT>true</PublishAoT>
    <InvariantGlobalization>true</InvariantGlobalization>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="PuppeteerSharp" Version="19.0.0" />
  </ItemGroup>

</Project>

// Program.cs
await using var browser = await PuppeteerSharp.Puppeteer.LaunchAsync(new()
{
    ExecutablePath = @"C:\Program Files\Google\Chrome\Application\chrome.exe",
});

Publish this as a standalone executable (e.g. dotnet publish -r win-x64 -o build), then run the executable.

Expected behavior:

A Chrome browser process is launched and connected. No exception thrown.

Actual behavior:

A Chrome browser process is launched, but failed to connect.
Exception thrown:
