Was in the same boat as you guys until I reset my WMI repository by finding another post that I can’t post a link to, but you can find a article by searching “blizzard resetting the wmi repository” The forum post told me to do it safe mode and the article doesn’t so I’m not sure safe mode is needed but it fixed the issue for me. Do you guys also have “allow multiple instances of battlenet” enabled? Curious if this error if these problems are due to that, although it has been working fine for me for months.
