[Remote Assets] Unity freezes when loading addressable sounds from a remote server

Hello, I'm facing this problem for a couple of months already, but as it hasn't been fixed in the new version of the addressables package I would like to bring this to your attention.
What happens is that every single time I try to load addressables from a remote server, if an addressable contains sounds or music, I get a pink screen and unity totally freezes. this only happens if play mode script is set to "Use existing build".
I have to add that if I compile the project and I run the game everything works just fine, the problem occurs only in the editor.

this is the console log before unity freezes:

Cannot create FMOD::Sound instance for resource archive
Function __cdecl SoundHandle::Instance::~Instance(void) may only be called from main thread!

I'm on Unity 2018.3
and the addressables package is on 1.5.1

 

As indicated by the error the cause may be that you are handing the file off to FMOD before it is loaded as the music file itself.

Try throwing some debugs in there to see when the addressable loads to it's asset.

 

I think this issue has to do with FMOD being used in editor mode and not being compatible with WebGL AAC audio format, which is the target build I'm using, causing the editor to freeze.
I've done some more test and I've stepped into this warning as well:

assets bundles built with build target WebGL may not be compatible with running in the editor.

anyway, it is super annoying having to close the process from the task manager because of unity freezes.
