Tested in Edge (Chromium)
Sometimes the map loads fine:

Sometimes it becomes unresponsive (other than scrolling to zoom and panning) on loading. This also seems to randomly happen when leaving the map open for a few minutes. When this happens the console is full of errors (these are coming in faster than I can scroll).

In this erorred state, clicking the top nav buttons to try to navigate away from the Map page does nothing or behaves unexpectedly.
For example, after letting the page load for a long time and clicking the Power nav button, it loaded React data as a text file?
It seems very inconsistent, sorry I don't have better reproduction steps. Save will be attached later today (I don't host the server)
