App crashes on HoloLens when using default WebView prefab from Microsoft.MixedReality.WebView 0.17.1-pre.5

[MisterL63]

The application builds successfully and runs fine in the Unity Editor, but it consistently crashes when deployed to a HoloLens 2 device.
This happens both when using the default prefab from the Microsoft.MixedReality.WebView (Preview) package (0.17.1-pre.5), and when manually adding the WebView component to a GameObject.

The issue occurs identically with:
MRTK 2.8 and MRTK 3

The crash happens every time, and the error is the same in all cases.

Unity version:
2021.3.28f1 or 2021.3.24f1

Note:
The error does not occur in the Unity Editor, and the build completes successfully without any warnings or errors. The crash only happens once the app is launched on the HoloLens 2 device after the compilation succes.
