I was trying to configure a KafkaNodePools functionality (and that's were probably working) using this guide -> click but now my cluster-operator falls with a error. How can I fix it?
> kubectl logs strimzi-cluster-operator-759856c456-lfxqx -n kafka

I was trying to fix it changing version of strimzi (because the internet said it could be a reason for a problem) but instead all my deployment has been crashed.

The KafkaNodePools feature gate has matured to GA and cannot be enabled / disabled anymore (the Kafka node pools are now always enabled). So you should remove it from the configuration. You can just remove the whole section:
- name: STRIMZI_FEATURE_GATES
value: +KafkaNodePools
