Perfetto UI - An unrecoverable problem occurred

If you are seeing this message, something went wrong while loading the UI.
In most cases this is due to very slow or flaky network and it goes away by
disabling and re-enabling WiFi or trying reloading.

If the problem persists try these remediation steps:

* Force-reload the page with Ctrl+Shift+R (Mac: Meta+Shift+R) or
  Shift + click on the refresh button.

* Clear all the site storage and caches and reload the page.

* Clear the site data and caches from devtools, following these instructions.

If none of this works, file a bug attaching logs and screenshots from devtools.
