Apologies for the chat spam, Im just wondering what else I am supposed to do after running

prefect server start

locally (which launches fine and gets me to the Welcome to PREFECT SERVER ascii splash screen). Navigating to localhost:8080 shows me connect to the server (and pull down the favicon+title) but the web page is empty (completely white). I can see its got content and scripts in the html, but theres this error and nothing is every made visible in the UI:

Same thing happend a few days back. I'm also experiencing the issue again: https://github.com/PrefectHQ/ui/issues/582#issuecomment-772408408

So time to roll back a tiny bit then, I see. Thanks mate!
