Hello there!
As a hotfix has been deployed by Nvidia to resolve this white-screen crash issue, we will now be marking this thread as "Resolved."
If you haven't yet installed the new update, you can find it here. We'd recommend that you ensure you have the most up-to-date drivers for your GPU installed before launching Assassin's Creed Valhalla again.
If you are continuing to experience a white-screen crash, even after installing the Nvidia hotfix, then please don't hesitate to update us within this thread so we can take a closer look.
If you are experiencing a crash without a white-screen, then I recommend you share your report within our dedicated Megathread for crashes / freezes in Assassin's Creed Valhalla.
Thanks!
