Hi, @lezzi!

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!

@lezzi Could you try navigating to microsoft.com, open a print dialog (ctrl+p) and check if its reproes with the site.

The dmp suggest that it was SmartScreen feature. Could you try to disable SmartScreen feature and see if it makes a difference? To disable SmartScreen, you could set IsReputationCheckingRequired to false after webview is created.

• I tried https://microsoft.com and it does not crash in the case of this website.
• Disabling IsReputationCheckingRequired didn't help 🤔

[monica-ch]

@lezzi Have you navigated after the smart screen is disabled? If it still reproes, please share the latest dmp.
