Heroes of the storm fail to be lounched!

Hi all,
I can’t understand why i fail to launch heroes of the storm version 2.47.3.76124 on my MAC ver. 10.14.6 . Basically when i launch it from battle net a message appears saying that the application unexpectedly crushed.
I’ve tried to uninstall Heroes and battle net and reinstall but won’t work.
I’ve noticed that on the shared file folder of my Mac accounts there are two folders; “blizzard” and “battle net” can this hinder the launcher?
Please let me know if i can provide more useful information.
Thanks.
