looks like same issue as https://github.com/reactiveui/ReactiveUI/issues/3786#issuecomment-2059046449

see if the following workaround prevents the issue. you need one of these in app initialisation before ReactiveUI is called.

if you're not doing any custom Splat DI config.

ReactiveUI.PlatformRegistrationManager.SetRegistrationNamespaces(RegistrationNamespace.WPF);

if you're doing any custom config to Splat etc. you'll need something along the lines of. (you might want this version anyway so it's clearer when ReactiveUI is being set up)

Locator.CurrentMutable.InitializeSplat();
Locator.CurrentMutable.InitializeReactiveUI(RegistrationNamespace.WPF);
