your useContext return null. And you try to destructure null. If you don't provide array in context provider value then you can't write:

const [a1, a2] = ....

So probably you miss match useState

const [state, setState] = useState

with context

const context = useContext(Context)

So. Just write:

const balance = useContext(BalanceContext);
console.log('balance context:',balance)

and then you will see what is in balance context. if is a object then you have to destructure object.

ps. quick fix to run project:

const [balance, setBalanace] = useContext(BalanceContext) || [];
// balance and setBalance is undefined
