WoW won't launch nor download

Hello, I went to log into WoW but it doesn’t work. It slowed down my PC and other programs and I had to restart. So after restarting, I went to disable my anti-virus and done other things just to launch WoW but still won’t. I deleted WoW and still can’t reinstall, I even reinstall battle.net but still somehow WoW is bugged. I tried everything, is there an issue for WoW, or what is going on? I even deleted addons. Although other games are working perfectly win like Wc3 and hearthstone but I don’t know why WoW is bugged. Please help, thank you.
