Hi @jujoco91 I can see that you have submitted a support case and are waiting for a reply.
I can confirm that due to the high volume of contacts it is taking longer than usual to reply, for which I apologise. Our Customer Support specialists will reply to you as soon as it is possible.
In the meantime the only other suggestion I have which appears to have worked for a number of players experiencing an issue with the game launching and being stuck on the splash screen is to add Assassin's Creed Valhalla to their exceptions list for their anti virus software. This is only a suggestion as I understand some players may be wary of this.
Please note if you decide to try this be certain to add the game to your exceptions list and do not disable your anti virus software altogether as this would leave your system vulnerable.
We have also created a megathread for the issue with the game being stuck on the splash screen and it has been reported to the development team who are investigating.
