looks like same issue as #3786 (comment)

---

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);
