Workflows aren't being run on this repository -- Private repo

Hi ,

After creating a private repo inside the Github Organization, i tried setting up a self hosted runner on the same repo.
For that i navigated My organization–> My private repo → settings–>Actions–> General(runners)–>Add Runner.

I am getting below message :

Workflows aren’t being run on this repository

Actions are not currently enabled on this repository. Configure a workflow file to enable Actions.

Same issue i am getting in my company’s organization’s private repo also.

Previously , i was able to add the self hosted runner to my company’s private repository, and now the same i am unable to do it.

Can somebody give me details on its fix? Has this issue occurred due to some patch ? or its bug related?
