Unexpected token '??=' when running a new project created with cargo create-tauri-app --beta

[MarcMouries]

I just created a new project created with cargo create-tauri-app --beta

I used the following options

✔ Choose which language to use for your frontend · TypeScript / JavaScript - (pnpm, yarn, npm, bun)
✔ Choose your package manager · bun
✔ Choose your UI template · Svelte - (https://svelte.dev/)
✔ Choose your UI flavor · JavaScript
✔ Would you like to setup the project for mobile as well? · yes

And I am encountering an error right after i try to run the project that was generated.

$bun run tauri dev
$ tauri dev
    Running BeforeDevCommand (`bun run dev`)
$ vite dev

Which bun version are you using?

[MarcMouries]

I am using Bun v1.1.20.
I tried again today and limited the options. I went with Bun and Vanilla and no Mobile and it worked this time.
Yesterday i had chosen Svelte and Mobile

Hmm, what about your nodejs version? ??= should be supported since 15.0 according to MDN.
