Cannot test with Profiler (Profiler.CollectGlobalStats 99.5% 8258ms)

I cannot test the game with the profiler recording in Unity 2017.4.9f1



The profiler just freezes the whole editor.

Am I doing something wrong here?

 

It also happens when I record with Profile Editor without being in Play mode.



I also have tried the solutions mentioned in this thread:

https://forum.unity.com/threads/2017-3-editor-overhead-performance-degradation.509821

But none of them worked.

I don't know where to look to find what the problem is (because the Profiler should be what I should look to know)

 

We managed to narrow the problem down to a list (in an asset) that we have.

We have a list of AudioClips that is causing this Profiler behabiour.
The problem is the size of the list that is almost 9000. Dividing this list into multiple sublist (9 list of 1000 or 90 list of 100) didn't solve anything.

How can we put that many AudioClips in a structure that could be used ingame without destroying the Profiler performace (and maybe the game performance)?
