What happened?
Description: When running a WebView2-based application built with C# targeting x64 on an ARM64 Windows machine, attempting to send large messages to the WebView2 control leads to deadlocks and eventual crashes of the entire application. This issue occurs in the following scenarios:
[ComVisible]method on a bridge between C# and JavaScript.CoreWebView2.PostWebMessageAsJson.CoreWebView2.PostWebMessageAsString.The application becomes unresponsive and eventually crashes, indicating a fundamental issue with the translation layer for WebView2 when running x64 applications on ARM64 Windows.
Expected behavior: The application should be able to send and receive large messages without any deadlocks or crashes, regardless of the target platform (x64) and the underlying architecture (ARM64).
Actual behavior: The application deadlocks when attempting to send large messages to the WebView2 control and eventually crashes, making it impossible to use WebView2 reliably in x64 applications running on ARM64 Windows.
Additional context: This issue is critical for developers targeting x64 applications that use WebView2 and need to support ARM64 Windows devices, especially since Steam only supports the x64 platform. The deadlocks and crashes make it impossible to use WebView2 reliably in such scenarios, severely limiting the usability of the control on ARM64 Windows machines.
Importance
Blocking. My app's basic functions are not working due to this issue.
