Magento 2.4: Catalog Search index exception: Could not ping search engine: No alive nodes found in your cluster

We have installed Magento 2.4 on our local machine. After installing, we have got the below error when doing the setup:upgrade

Could not validate a connection to Elasticsearch. No alive nodes found
in your cluster

So we have disabled the elastic search module via config.php. After disabling the elastic search, we can successfully upgrade and run the deployment without any issues.

However, we are not able to create a product in admin as its keep loading and getting the below error in console.

enter image description here

We have try reindex but the below indexer is not running.

Catalog Search index exception: Could not ping search engine: No alive
nodes found in your cluster

Please help me to resolve this issue.
