Resolution Note:
This is because the URP Sample does not have "run in background" ticked in the Player Project Settings (see the related comment for a screenshot with the option in).
With that option unticked, when the standalone profiler is the foreground app the Editor will stop running the game and the framerate shown will be lower.
If you tick that checkbox then the sample updates properly when the standalone profiler is in the foreground and the framerate should be higher again.
