Describe the bug 🐞

I'm not sure exactly which one caused that, I updated the packages ReactiveUI and ReactiveUI.Blazor from 20.1.63 to 21.0.1 and also DynamicData from 9.2.1 to 9.4.1 (which I use together).

It seems to work in debug mode, but after publishing (which I know Blazor also do trimming) I'm getting a Arg_PlatformNotSupported exception, which didn't happen before.

(null) blazor.web.js:1:158912
