[Bug Report] Diablo 4: Game initialization Failed: U

Technical Support
1

Hello everyone,

I have logged in about 30 minutes ago into Battle net and then the Diablo 4 client started an update. After the update I tried to start the game but I keep getting the same error “Game initialization Failed: U” and the game is not starting. I must mention that previous to the update the game was working fine.

Please let me know how to proceed.

Thank you

I also have the exact same issue.
It is the first time for me to launch the game though.

Here are some things I tried to no avail :

  • Creating exceptions for Diablo 4 (app & launcher) and battle.net for my firewall and antivirus.
  • Re-install Diablo 4
  • Remove VPN
  • Repair Diablo 4
  • Update my drivers but they are all up to date already
  • Update D4 but it is already up to date
  • Run D4 as an administrator

I honestly don’t know what more to do :frowning:

Same problem but it happened after installing Kaspersky Antivirus, so I believe that’s the cause. The problem is I am WFH and have Diablo installed on my work PC, with no control over the AV software.
