RabbitMQ: "All stable feature flags must be enabled after completing an upgrade." - How to fix?

I have just installed RabbitMQ on a fresh Windows 11 installation and enabled the management plugin by running the command rabbitmq-plugins enable rabbitmq_management in the RabbitMq command prompt.

When I navigate to the RabbitMQ management website in my browser I see the following message:

What is the cause of this error message? And how do I fix the issue?

I'm using RabbitMQ version 3.13.3 with Erlang 27.0. I have not yet created any queues or users in RabbitMQ.

Edit: When I run the command rabbitmqctl list_feature_flags I get the message Error: {:badrpc, :nodedown}. So I can't simply list and enable feature flags.

The issue turned out to be twofold.

1. The first part of the issue was that I could not simply run the command rabbitmqctl list_feature_flags to see what feature flags were enabled or not. The command would return the error Error: {:badrpc, :nodedown}. Running the command rabbitmqctl status revealed the error: TCP connection succeeded but Erlang distribution failed, which has a solution here. I needed to synchronize the Erlang cookies and then the rabbitmqctl status command worked fine.
2. After fixing the Erlang cookie synchronization, the command rabbitmqctl list_feature_flags works fine and lists enabled/disabled features. It was then a simple matter of enabling features with the command rabbitmqctl enable_feature_flag <feature_name>. See more documentation on enabling features in the docs.
