That part is the key here. Since 3.7.0 the cache API has had said contains method. So it seems like when this was reported there was a bad upgrade, or even worse potentially something overloading the cache API.
@mbabker can you take a look here as you was able in the past to set up a redis server. By reading the code it looks like
$callbackis a object but not callable so maybe we need to do a extra is_object check? But i also don't understand where this is not callable object comming from.
