I have that a few months ago, rebooting the console fixed it.
(Press and hold both thumb wheels until the screen goes blank and the Tesla logo comes back)
What firmware are you running? I had this issue way back in 2018.50.6 release (and just before that), but I can't recall the last time I've seen that with a 2019 release...
Resetting the trips (apparently a memory hog) fixed this for me It also made the browser usable again! Also told that deleting old nav destinations helps.
