How to understand the output of the Unity profiler?

Question

Unity

Good afternoon!
The program developed in Unity slows down (freezes for a few seconds when one of the scripts is launched) on an old Android device (Samsung J1 mini). Works fine on newer ones. I decided to try to figure out where the bottleneck is. Launched a profiler and understood nothing. ((
Firstly, the profiler itself hangs along with the device, and after hanging some particularly high load peaks, I don’t see it. At the moment of freezing, the profiler gives me this picture:

Is it possible to understand from this what specifically caused the hang, Or which way to dig?

Answer 1

Cut off the output to the console of a ton of garbage in the prod.
