React useState hook affecting default variable used in state regardless spread operators, Object.assign and etc

I am experienced js/React developer but came across case that I can't solve and I don't have idea how to fix it.

I have one context provider with many different state, but one state looks like following:

const defaultParams = {
  ordering: 'price_asc',
  page: 1,
  perPage: 15,
  attrs: {},
}

const InnerPageContext = createContext()

export const InnerPageContextProvider = ({ children }) => {
  const [params, setParams] = useState({ ...defaultParams })

  const clearParams = () => {
    setParams({...defaultParams})
  }

  console.log(defaultParams)

  return (
    <InnerPageContext.Provider
      value={{
        params: params,
        setParam: setParam,
        clearParams:clearParams
      }}
    >
      {children}
    </InnerPageContext.Provider>
  )
}

I have one button on page, which calls clearParams function and it should reset params to default value. But it does not works

Even when i console.log(defaultParams) on every provider rerendering, it seems that defaultParams variable is also changing when state changes

I don't think it's normal because I have used {...defaultParams} and it should create new variable and then pass it to useState hook.

I have tried:

const [params, setParams] = useState(Object.assign({}, defaultParams))
const clearParams = () => {
  setParams(Object.assign({}, defaultParams))
}

const [params, setParams] = useState(defaultParams)
const clearParams = () => {
  setParams(defaultParams)
}

const [params, setParams] = useState(defaultParams)
const clearParams = () => {
  setParams({
    ordering: 'price_asc',
    page: 1,
    perPage: 15,
    attrs: {},
  })
}

None of above method works but 3-rd where I hard-coded same object as defaultParams. The idea is to save dafult params somewhere and when user clears params restore to it. Do you guys have some idea hot to make that?

Edit: This is how I update my params:

const setParam = (key, value, type = null) => {
    setParams(old => {
      if (type) {
        old[type][key] = value
      } else old[key] = value
      console.log('Params', old)
      return { ...old }
    })
  }
