Yes, please! Just ran into this.

Is this only a Fable 4 problem?

I'm seeing this same error also on Fable 3.7.18 - 3.7.20.

What's going on?

[et1975]

We've been in beta for too long it seems, the elmish package reference allows for pre-releases, new v4 subscriptions haven't been implemented for HMR yet. Try referencing earlier elmish (beta-1) explicitly in your project and consider using lock files to avoid picking unintended upgrades.

@et1975 Thanks. It turned out that "nuget Fable.Elmish.HMR ~> 6.0.0-beta-002" works fine even with Fable 3.7.20.

I just had to avoid running paket install because it upgraded other React & co. packages, which consequently broke HMR.

Version 6.0.0-beta-003.nupkg has just been released, it should now support the latest alpha of Elmishv 4.

Thanks @kspeakman for his work on it.
