My scripts are not working properly
So my scripts come in three parts 1st part is Keybind 2nd part is KeyController and finally the 3rd part is function i want done if key is pressed. But issue is KeyController isnt pulling Keybind scripts unless object in the inspector is selected during play mode. If i pause it then select Object that has scripts on it after i resume it magically works. Its important to note if Main Object that has codes is selected then scene is played it still has these errors
Errors

for (int i = 0; i < KeyCS.KeyCS.Length; i++)
{
if (KeyCS.KeyINFO[i].KeyName == "Inventory" && !KeyCS.MenuLock)
{
if (Input.GetKeyDown(KeyCS.KeyINFO[i].Key))
{
showinven = !showinven;
}
}
else
{
break;
}
}
}
}
quick comment to add is that errors occur twice if object that has scripts applied to it is selected in the inspector when play mode is pressed and then all the scripts are fully functional one again I have tried doing if else return method as well as if null else neither of these have worked
