Description
What happened?
I wondered why all my WebView2 windows stop working today even though everything worked yesterday. It turns out that 138.0.3351.77 was installed last night around 9:17PM before I restarted my app.
ICoreWebView2Environment10.CreateCoreWebView2ControllerWithOptions now returns CO_E_SERVER_EXEC_FAILURE in the callback no matter what I do. Nothing will load now.
Importance
