Cluster has already maximum shards open

Elastic Stack Elasticsearch
1

I'm using Windows 10 and I'm getting

Elasticsearch exception [type=validation_exception, reason=Validation Failed: 1: this action would add [2] total shards, but this cluster currently has [1000]/[1000] maximum shards open;]

How can I resolve this? I don't mind if I lose data since it only runs locally.

You've hit the limit of the maximum number of shards per node.

Either remove some indices from your cluster or add a new node to your cluster.
