--- Comment #23 from Pavel 89807457050@mail.ru --- 5. Probably it's Agent (aka battlenet-update-agent, aka Agent.exe) problem. Error from wow lead to https://eu.battle.net/support/en/article/cannot-communicate-with-battlenet-u... and I "Try manually updating Agent." It become an error. It didn't work. Wow probably start this agent at 90%. Agent have bug which crush Agent, then Agent crush wow.
My path to game /media/<user>/<HD name>/<folder1>/<folder2>/<wow folder>
I hope it help
