CORS issues when using multiple local apps (localhost:<PORT>) to hit the same dev okta account

They are both listed and I think there’s some wires getting crossed because of it. My issue is the same as this other issue created a few weeks ago:

Once I added my second localhost:PORT combo, both apps started getting the same error. I clear browser cache and one begins to work, until I try to hit the auth flow with the other, and then I’m back to getting that error for both applications.

Thanks for the reply
