就报错:

Research direction

Start with the minimal Python repro using pywebview 5.3.2 on Windows 10, then trace the WebView2 initialization stack shown in the report. Compare the reported Microsoft Edge WebView2 Runtime 130.0.2849.52 environment with the stated framework and OS details. Done means the example window opens without the initialization exception.
