    I upgrade unity from 2018.2.21f to 2018.4.29f. In the new version, it takes almost 5 minutes to go into play mode first time, even in empty scene. But new empty project is fine. I recorded the log output of the editor in play mode first time.
    Any help would be super appreciated.

    I caught it. This is the profiler's screenshot. ApplicationTickTimer takes 316,985ms.

    Well, that selected sample makes up some 7ms of that frame time so I doubt that's the main issue here. You might want to sort the hierarchy by the time taken for each sample and focus on those taking the biggest chunk out of the enter Playmode time.
