Hey everyone,
Thank you for reporting these sudden issues launching the game. This delayed and/or non-responsive behavior is commonly caused by outdated antivirus software, so be sure that you’ve fully updated any antivirus programs you’re running alongside the game – otherwise it might block it due to the new client build changing. If that doesn’t work, uninstall the antivirus program temporarily, reboot your computer, and then retest.
Note: Some security programs may be difficult to uninstall. ESET maintains a comprehensive list of common antivirus uninstallation tools on their website.
