Welcome to Microsoft Q&A!
Could you please provide a code sample to help us further check the problem for you?
What version of Webview are you using? Webview or Webview2?
Thank you,

Is
web.InvokeScriptAsync()not getting the correct result? Have you tested your java script in browser(Edge) to get the correct result?If possible, could you please provide a reproducible example that would help to explain what your issue is?

2023-05-11T10:07:35.61+00:00 Your description is a bit confusing.
Which control do you need to use now? WebView2 or WebView? What's the real problem now? Could you please explain concisely.
