Description
Description
On one of our machines CreateCoreWebView2Controller completion handler (ICoreWebView2CreateCoreWebView2ControllerCompletedHandler) returns 0x8000ffff and as a result WebView2 initialization fails.
User data folder is created successfully and some msedgewebview2.exe processes are created, but I noticed that at least one of them exit with 0xC0000409 code (STATUS_STACK_BUFFER_OVERRUN).
I tried capturing crash dump by enabling WER registry key, but no dump was created and nothing ever logged to Event Viewer.
I also tried to reinstall WebView2 runtime but still same result.
Are there any WebView2 logs somewhere to indicate what exactly failed during initialization?
