Possible parse error: non-abstract method defined as abstract

It is generally advisable to only define one property per statement.

$this->disregardThrowable(); does not seem to be reachable.

Consider making the type for parameter $args a bit more specific; maybe use array.

            $this->setThrowable(new EnsuranceException(format($message, ...$args), $this->throwable));
