Webview2 WPF does not render content in x86 mode when launched from Excel - Fixed and Evergreen Runtime

Description
No errors thrown, but the window only shows up as blank (there is a foreground message indicating a page is loading however), and right-click and Inspect shows the content is loaded, just not rendered

Version
SDK: 1.0.774.44
Runtime: 89.0.774.63 (also issues with Evergreen)
Framework: WPF, .NET Framework 4.7.2
OS: Windows 10

1. Install both x86 and x64 Evergreen
2. Use sample solution -> https://github.com/theboyknowsclass/WebView2Bug
3. Have both x64 and x86 versions of Excel installed (I was using Microsoft 365 for 64-bit), and 15.0 - 32-bit
4. Debug the app in x64 mode

Expected Result: window should appear with google
Actual Result: window appears with google - yay!

5. Debug the app in x86 mode (you may need to specify the x86 exe in Project Properties -> Debug -> Start External Program)

Expected Result: window should appear with google
Action Result: blank window appears :( - although content is present when right-clicking in the window and selecting Inspect, so it is loading, just not rendering

Start with the linked WebView2Bug sample solution and reproduce the x64 and x86 debug paths from Excel on Windows 10, using the listed WPF and .NET Framework versions. Compare the blank x86 window with the working x64 case and verify rendering through the visible page and Inspect action; the issue title indicates this may already be fixed.
