Hello,
I have the same issue unfortunately.
Edition Windows 11 Enterprise
Version 24H2
Installed on 27-Oct-24
OS build 26100.3194
Experience Windows Feature Experience Pack 1000.26100.48.0
I don't get any error on screen or in event viewer. I tried disabling my AV with no luck. Files check tells me it's all good, the game will just get past login, I see the anticheat passing without issues, aion small icon loading appears, yet after 5 seconds both aion small icon for game loading and the aion process from task manager suddely dissapear without any warning / error / event viewer issue.
Is this new? I have been able to play on my 23H2 installation.
