First of all, thanks for providing your system files and a list of steps you have tried! This definitely helps speed up the troubleshooting process.
At the moment, there aren't any known problems causing this for Windows 11 specifically and these problems can happen for several different reasons and can be difficult to pin down.
The most common cause for these issues though is background programs like security software preventing the app from connecting or the games from launching. I noticed you have Norton so let's try adding the Blizzard app and game folders as an exception in Norton:
-files-from-norton-antivirus-scans-153348
If that doesn't help, try uninstalling Norton temporarily then restart the PC. You can always reinstall Norton again afterwards once this is resolved:
=norton&site=nrtn_en_US
If this persists, please email the Blizzard app error logs to tech...@blizzard.com with US88941759 in the subject line:
