ASP.NET Core error when I want to use Playwright

I am trying to create some PDF generator service. For that I would like to use Playwright. I create some test to see is it working, but I got the following error:

Executable doesn't exist at C:\Users\wasys\AppData\Local\ms-playwright\chromium_headless_shell-1148\chrome-win\headless_shell.exe

This would be my service:

public class PdfgeneratorService(IServiceProvider serviceProvider, ILoggerFactory loggerFactory) : IPdfgeneratorService
{
    public async Task GeneratePdf<[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.All)] TComponent>
                        (string fileName, Dictionary<string, object?> htmlData) where TComponent : IComponent
    {
        await using var htmlRenderer = new HtmlRenderer(serviceProvider, loggerFactory);

        var html = await htmlRenderer.Dispatcher.InvokeAsync(async () =>
        {
            var parameters = ParameterView.FromDictionary(htmlData);
            var output = await htmlRenderer.RenderComponentAsync(typeof(TComponent), parameters);
            return output.ToHtmlString();
        });

        using var playwright = await Playwright.CreateAsync();
        //ERROR IS APPEARING IN THIS LINE
        var browser = await playwright.Chromium.LaunchAsync(new BrowserTypeLaunchOptions
        {
            Headless = true
        });

        var page = await browser.NewPageAsync();
        await page.SetContentAsync(html);

        await page.PdfAsync(new PagePdfOptions
        {
            Format = "A4",
            Path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), $"{fileName.Replace(".pdf","")}.pdf")
        });

        await page.CloseAsync();
    }
}

In the test library I created a test and used a code provided by Nick Chapsas in his tutorial.

public class PdfgeneratorServiceTests
{
    private PdfgeneratorServiceTestBuilder builder;

    public PdfgeneratorServiceTests()
    {
        this.builder = new PdfgeneratorServiceTestBuilder();
    }

    [Fact]
    public async Task GeneratePdf_Success()
    {
        var invoice = InvoiceGenerator.Generate();

        var htmlDictionary = new Dictionary<string, object?>
        {
                { "Invoice", invoice }
        };

        var exception = await Record.ExceptionAsync(async () =>
            await builder.PdfgeneratorService.GeneratePdf<InvoiceView>("Test", htmlDictionary)
        );

        Assert.Null(exception);
    }
}

I also tried to add a PostBuild script in my PdfGenerator library.

<Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="powershell.exe -Command $(TargetDir)playwright.ps1 install chrome;" />
</Target>

When I tried to build this library, I got an error:

Exception calling "ReadAllBytes" with "1" argument(s): "Could not find file

In the bin/debug/net9.0 folder I have a playwright.ps1 file and a .playwright folder (if this helps).
