Can't successfully change the GitHub repository linked to my worker

The worker is connected to the repo personal-page2, but I want it to use personal-page now instead. I first tried going to the repository access settings in GitHub's Applications, and replaced the old repo with new one. Seems like it's not the right way to go, as the re-deployment just doesn't proceed now + there's this internal issue alert (in the attached screenshot). Is there a way to change the repo of the worker without deleting it? Thanks in advance :)
