Unsupported OCaml version 4.10.0

A couple of days ago I was working on a project in vscode using this extension, and when I came back today I'm getting a message "Unsupported OCaml version 4.10.0", cannot save because I guess it's trying to access my ocaml version, and totally freezes the editor since it cannot get it. I haven't changed anything, but I only have one version of ocaml installed and it's 4.09.0, not even 4.10.0. Is this a known issue? Here is my logs that the template requested:

```

Start with the reported extension 1.7.8 logs and the bin.native entry point, then compare the esy/dune project setup with the installed OCaml 4.09.0 version. Check the bsconfig.json cleanup and the repeated “Unsupported OCaml version: 4.10.0” message. Done means the language server recognizes the installed version and no longer freezes VS Code.
