[Problem/Bug]: Multiple Browser Instances Sharing User Data Folder Cannot Have Different Settings #4593

Open vrad-joshuamckelvey opened 1 month ago

What happened?

WebView2 fails to launch when two WebView2 browser instances are sharing the same User Data Folder with differing CoreWebView2EnvironmentOptions.AllowSingleSignOnUsingOSPrimaryAccount values.

The second browser throws the error below:

System.Runtime.InteropServices.COMException: 'The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F)'

Importance

I can provide a demo application as well if that would help.

It should be by design - it is browser feature. If you are running wv2 with the same UDF they share browser process. Could you please double check that it is working in 124?
