Warum stürzt meine .NET MAUI iOS-App mit System.ExecutionEngineException unter IOS mit einem JIT-Kompilierungsfehler ab? ⇐ IOS

[Anonymous]

Ich erstelle eine .NET MAUI Blazor-App, die statische Dateien (CSS, Bilder und index.html) im wwwroot-Ordner verwendet.
Die App funktioniert einwandfrei auf Android und, aber unter iOS stürzt sie beim Start mit dieser Ausnahme ab:

Code: Select all

System.ExecutionEngineException
Attempting to JIT compile method '(wrapper dynamic-method) object object:InvokeStub_SafeFileHandle..ctor (object,object,intptr*)' while running in aot-only mode. See https://learn.microsoft.com/xamarin/ios/internals/limitations for more information.
