MacOS name not found when installing JavaScriptCore

[caraya]

I'm running on a M3 Pro laptop running the latest version of macOS (Tahoe 26.0.1) but I'm getting the following error.

✔ Read OS from config: mac64arm
✔ Read engines from config: javascriptcore, spidermonkey, v8
❯ Finding the latest JavaScriptCore version…
✖ Error: Unknown MacOS name: tahoe.

Trying to understand what's causing the problem and whether it's hardware related or a problem with JSVU itself.
