This error is fairly self-explanatory and straight forward, isn’t it? Your minimum value can’t be greater than your maximum value.
It would be helpful if you had posted relevant code samples or debugged this yourself first before asking, because this may be due to an oversight in your code and not because of a Roblox update (which would have almost no impact). Add print statements around and check what is being printed (e.g. print the maximum and minimum before the DataStore fetch on Line 102).
