Sudden Game Freezing/Lag Spikes

Ever since updating the game to 1.20 it freezes frequently and there is constant lag spikes I thought that it would be fixed in the upcoming updates but it has been 6-7 months and this bug still exists it is really annoying to play because of this bug. (I have a pretty good device and uninstalled and reinstalled the game multiple times my friends also play mcpe and they also face this problem).
