Wpf App crashes with version 141.0.110

[AlexBLoesch]

I am developing a Wpf app with .net Framework 4.8 and x86. My app contains the WebBrowser to navigate to an Url like http://localhost:3000.
The app is running inside a Windows Kiosk Mode by using the ShellLauncher. The Kiosk mode is running inside a windows guest account.
The Cef.Sharp version 126.2.180 was working in this setup without any issues.

Now I updated Cef.Sharp to version 141.0.110 by using Nuget and my app crashes without any error prompt everytime I want to use the WebBrowser. If I switch to a common windows administrator (leaving the Kiosk mode), my app is working properly and is displaying the website.
I found an event viewer entry related to this behavior, but I don't get, what is saying.

My setup is:
Windows 10 IoT or Windows 11 IoT
My app contains a app.manifest according to the docs.
I am initializing the Cef.Sharp.
Windows Kiosk Mode as described above.

Just let me know, if there are further information needed.

Thanks for your support.

Greetings,
Alex

Sounds a lot like you are missing correctly configured app.manifest see #5173 (comment)

Confirm that Cef.AssertIsWindows10OrGreater() succeeds.

Otherwise you'll need to get a crash dump and analyze the dump file.

The same issue should have debugging links

Thanks a lot.
Calling Cef.AssertIsWindows10OrGreater() before Cef.Initialize(...) fixed the issue.
