please help me to solve this problem on my unity, I have tried but no result.
>Solution :
You named 2 variables "instance". Rename one.
edit:
your code shows:
private static DataHandler instance;
public static DataHandler instance;
my suggestion would be to either remove one of them (cause I don’t think this makes any sense) or to rename one:
private static DataHandler _instance;
public static DataHandler instance;
