[Problem/Bug]: Render process exited before DOMContentLoaded event

[YukiiOyama]

What happened?

My wpf application is not working on a client PC.
This app works fine on other PCs.

In a client PC, the ProcessFailed event is raised.
Other PCs, the ProcessFailed event is not fired and the DOMContentLoaded event is raised insted.

ExitCode = 3
Reason = Crashed
ProcessDescription = (blank)
ProcessFailedKind = RenderProcessExited

No crash report is created in '(UDF): \EBWebView\Crashpad\reports'.

Importance

Blocking. My app's basic functions are not working due to this issue.

@YukiiOyama could you please collect an ETW trace of the repro (https://github.com/MicrosoftEdge/WebView2Feedback/blob/main/diagnostics/etw.md) and share with lzhao@microsoft.com?

Please note that RendererCodeIntegrity feature has been deprecated from Chromium and "--disable-features=RendererCodeIntegrity" will be ignored, and there should be no space between disabled features. In your case, you might want to update the switches to be "--disable-features=msWebAppWidgets,msEdgeHubAppDesigner,msEdgeDesignerDriverFix,msWebView2CancellableAboutNavigations".

[YukiiOyama]

Thank you. I'll try.

@LiangTheDev
I could not get client's ETW trace, but I was able to check the client's PC by connecting remotely.
My app in that PC was checked Windows compatibility mode. So I turned this check off, then the app worked fine.
Thank you for your reply.

Closing the issue as the app works now.
