I came home yesterday to error BLZBNTBNA0000000C on the desktop app (beta version), saying " We couldn’t verify the digital signature of your Battle.net Agent". Tried all the steps in the help article. When I try uninstalling the desktop app via the normal Windows uninstaller, I get error BLZBNTBNU00000006, and it won’t let me uninstall.
I had made zero changes to anything on my system before this started, and I don’t run any security/anti-virus software outside of the default Microsoft stuff.
No clue how to proceed here.
