The error message "KV Store is initializing. Please try again later." in Splunk's Enterprise Security (ES) usually occurs when the Key-Value (KV) Store, which is a storage technology used by ES for fast data retrieval, is not fully initialized or is experiencing some issues during initialization. This can happen during a Splunk restart or after an upgrade. The KV Store needs to be up and running before you can access certain features in ES, including the incident review.

To resolve this issue, follow these steps:

1. **Wait and Retry**: As the error suggests, try waiting for some time and then retrying to access the incident review. Sometimes, the KV Store might just need a little more time to finish initializing.

2. **Check Splunk Status**: Ensure that Splunk is running and fully operational. Check for any potential issues in the Splunk logs or monitoring tools.

3. **Verify KV Store Status**: Verify the status of the KV Store and make sure it is healthy. You can do this by going to Splunk Web and navigating to "Settings" > "KV Store" > "Status." Check if all the components of the KV Store are running without any errors.

4. **Check Storage**: Ensure that there is enough storage space available on the system where the KV Store is located. Insufficient storage could cause initialization problems.

5. **Restart Splunk**: If waiting and retrying didn't work, try restarting Splunk. A fresh start can sometimes resolve initialization issues.

6. **Check for Splunk Updates**: Ensure that you are using the latest version of Splunk and the Splunk Enterprise Security app. Updates often contain bug fixes and improvements that could address this issue.

7. **Review Logs**: Check the Splunk logs for any specific error messages related to the KV Store initialization. This can give you more insight into what might be causing the problem.

8. **Rebuild KV Store**: As a last resort, you can try rebuilding the KV Store. This will recreate the KV Store from scratch, and it might resolve any underlying issues.

Remember, before taking any actions like restarting or rebuilding, it's always a good practice to back up your data and configurations.

If the issue persists after trying the above steps, it's best to reach out to Splunk support for further assistance. They can provide more in-depth guidance based on the specific version and setup of your Splunk environment.
