Thank you for reporting this bug, I was able to replicated with the latest update.
I'm sorry for the inconvinience. I will try to fix this asap and get back to you once I have a solution. And we will update the packages with the fix as soon as possible

Hello sorry for the delay.

The issue was quite simple. The array was not initialized before it was accessed causing the null exception error. I think this was caused either by a Unity update or an update on our part, skipping a scene saved after the character is setup and before the second step of setting up the inventory fo the character.
Normally if you closed and reopened Unity it would have worked.

But in any case here is the code fix in the ObjectAmounts.cs script:

    /// <summary>
    /// The base class of amounts array of an object.
    /// </summary>
    /// <typeparam name="T">The object type.</typeparam>
    /// <typeparam name="Ta">The object amount type.</typeparam>
    [System.Serializable]
    public class ObjectAmounts<T, Ta> : IReadOnlyList<Ta>, IObjectAmounts<Ta> where Ta : IObjectAmount<T> where T : class
    {
        [Tooltip("The array of object amount.")]
        [SerializeField] protected Ta[] m_Array = System.Array.Empty<Ta>();

        public Ta[] Array => m_Array;

        public int Count => m_Array?.Length ?? 0;

It will be part of the next update
