Please help
One of my raiders is suffering from this as well. We’ve tried:
Restarting the computer
Running Wow from the .exe
Restarting Battle.net
Logging out of and into Battle.net
Deleting the Battle.net Cache
Scan & Repair of Game Files
Ran the System File Checker
Full uninstall/reinstall of wow
None of the above assisted. Not sure what to suggest that he try next
Try to launch the game, then open the Task Manager to the Processes tab (it may be the default). Look in that list to see where the WoW executable is - if it’s under Background processes (the second section) then something is preventing it from launching properly, most probably at the driver level.
Unfortunately this is not an easy situation to resolve in my experience. When my system would occasionally do this I was able to track this behaviour back to a virtual input device - specifically the one provided by DS4Windows (a tool used to make a DS4 controller behave as an XInput device), which I could restart to momentarily correct it and later update to provide a more permanent solution. This was only possible through the log on a different program which showed the stall during startup, though it was so long ago now that I no longer recall which program it was.
Still, perhaps someone else may have another idea if this is what’s happening in these cases.
Troubleshooting is easier when DxDiags or MSInfos are provided. Pastebin.com is a good place to host them.
Just in case this helps the other player that was stuck on thus issue, the raider in my guild finally did get it fixed. An In-Place Upgrade of Windows 10 (See this support article - https://answers.microsoft.com/en-us/windows/forum/all/how-to-perform-an-in-place-upgrade-with-windows-10/7f0b236e-3c6c-4913-9691-c4baa2a6190a) fixed it for him.
