[Problem/Bug]: File / Folder Browse dialog opening can cause an AppCrash
IDS-Skunkworks opened this issue · 2 comments
What happened?
When a WebView2 control is embedded in a WinForms App and used to display web pages, clicking a control in the web page that causes a file/folder browse dialog box to open (for uploading files/folders to SharePoint, for example), the App hosting the WebView2 control can experience a crash to desktop with EmbeddedBrowserWebView.dll logging exception code 0x80000003 (ERROR_PATH_NOT_FOUND) if the dialog is trying to display a location that no longer exists (a deleted folder) or is inaccessible (disconnected network drive). This has been experienced on version 131.0.2903.99 of the WebView2 DLL.

Hi, @IDS-Skunkworks!
It seems that your issue contains the word "crash". If you have not already, could you attach a crash dump as a comment?
WV2 crash dumps are located in a subfolder of the app's user data folder (UDF): <UDF>\EBWebView\Crashpad\reports\. By default, the user data folder is created in the app's folder with a name like <App Exe Name>.exe.WebView2. Refer to Crash Diagnostics for more information.
Thank you for your cooperation!

Hi,
Just reproduced the issue and unfortunately that folder is empty so there is nothing to attach, sorry.
