Your dependency on mobx-react-lite is causing the issue. It only supports React 16.8+ to 17.x. It appears you've got React 18 installed, which contradicts the mobx-react-lite requirement and that's causing a version restriction that then conflicts when you try to install something that supports React 18.

You likely have multiple versions of react in your tree, which you can find with npm ls react.

This is what I see. I'm using preact. Would downgrading my preact version fix this error?
Edit: I dont think downgrading preact would be the best option. I think I need to serach for mobx-react-lite alternative 🙁
Edit2: I think I will just move from preact to react and downgrate to react 17 for now :( I will mark this as resolved as this isn't a problem with this package. Thanks!
