What happened?

I cant use WebUI offline anymore after the last big Update from a few days ago.
Gradio hangs, showing only rotating squares when you open WebUI-URL.

Its looks like it tries to access following css indefinitely and doesnt work without an access to those:
https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;600&display=swap
https://fonts.googleapis.com/css2?family=Source+Sans+Pro:wght@400;600&display=swap

Steps to reproduce the problem

1. Go offline
2. start "webui-user.bat" and wait until "Running on local URL: http://127.0.0.1:7860" shows up
3. start browser, go to above URL
4. look at the rotating squares in browser indefinitely

What should have happened?

4. WebUI Interface should have opened
