I fail to run widows appium sample test

I downloaded every item nessesery, am running the windows application driver and trying to run the up to date sample UI tests.
WAD produces this:
```POST /session HTTP/1.1
Accept: application/json; charset=utf-8

{"status":100,"value":{"error":"invalid argument","message":"Bad capabilities. Specify either app or appTopLevelWindow to create a session"}}
```

I get this error from maui-samples\9.0\UITesting\BasicAppiumNunitSample\UITests.Windows\AppiumSetup.cs:line 34

`OpenQA.Selenium.WebDriverArgumentException: 'Bad capabilities. Specify either app or appTopLevelWindow to create a session'`

What am I doing wrong? Might the sample app be broken?

Start at maui-samples\9.0\UITesting\BasicAppiumNunitSample\UITests.Windows\AppiumSetup.cs line 34 and inspect how the Windows Appium session capabilities are configured. Reproduce the POST /session request with the current sample and compare it with the Windows Application Driver error. Done means the sample creates a session successfully and its UI tests run.
