[Problem/Bug]: Navigating to certain URI schemes (e.g. mailto:, calculator:, res:) causes the webview2 process to crash at specific conditions

[jls28]

open any page, then navigate to mailto:test : work as expected (a dialog prompt appear), then, without reloading or changing the page, navigate again to mailto:test : this crash the wv2 process.

note : add_LaunchingExternalUriScheme is not used.

the same thing happens with "calculator:", "ms-settings:", "tel:", at first navigation, a prompt dialog appear, at second navigation, the process crash.

and also "res:" crash the process immediatly at first navigation.

Probably there are others.

wv2 137...93

Hi, @jls28!

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!
