[🐛 Bug]: webview seems not to be detected in 4.33

[tiramba]

Description

For our test automation we want to attach to an existing instance of the edge webview (embedded).
With selenium 4.32 it worked as alwys with the following debug outputs:

DEBUG Sending stats to Plausible: Props { browser: "webview2", browser_version: "", os: "windows", arch: "amd64", lang: "csharp", selenium_version: "4.32" }
DEBUG msedgedriver not found in PATH

After the update to selenium 4.33 we have now the following error message

error in HandleBrowserException|OpenQA.Selenium.NoSuchDriverException: The browser path is not a valid file: C:\Program Files (x86)\Microsoft\EdgeWebView\Application; For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors/driver_location

with the debug logs

DEBUG Sending stats to Plausible: Props { browser: "webview2", browser_version: "", os: "windows", arch: "amd64", lang: "csharp", selenium_version: "4.33" }
DEBUG msedgedriver not found in PATH

Browser path: C:\Program Files (x86)\Microsoft\EdgeWebView\Application

both runs were performed on different but identical machines (created by the same template).
You can see on the last line of the debug logs, that the filename and the folder with the version is missing.

It seems to me, that this is a bug in the new version 4.33! Can you please have a look on it?

Reproducible Code

var eo = new EdgeOptions { UseWebView = true, DebuggerAddress = $"localhost:{Port}" };
Driver = new EdgeDriver(EdgeDriverService.CreateDefaultService(), eo, TimeSpan.FromMinutes(3));
