2020 4runner started making a squealing noise

[KingsCrossing]

my 2020 4runner with 300 miles on it started making a squealing noise that only happens when the car is in motion but doesnt happen all the time. I went to the dealer today and no one could figure out what the noise was after playing a video I made of the noise. of course the noise didnt happen at the dealer. any idea what this could be?
