Post this for future people:
This might be specific to my company’s network but, for me, Webex Teams (which is like Slack) was the culprit. I think they are trying to use the same TCP port or something. I installed and uninstalled Webex Teams multiple times and was able to recreate this issue multiple times. I removed Webex Teams and that fixed the issue.
If you have a Slack-like IM program, try uninstalling that.
