This test relies on Blazor internal implementation details (internal type name Microsoft.AspNetCore.Components.ChangeDetection and private static field _immutableObjectTypesCache, plus a concrete ConcurrentDictionary<Type, bool> shape). Because CI uses a floating SDK (10.0.x), a framework patch could rename/move the type/field or change the cache type and cause unrelated test failures. Consider rewriting the assertion to validate unload without depending on private runtime fields (e.g., keep a WeakReference to a dynamically emitted type/assembly, dispose the component, force GC, and assert it can be collected), or at least tolerate missing/changed members by conditionally skipping/failing with a clearer message.
