I did a clean reinstall of the latest driver, reboot and issue continues. I'm not sure what changed between this morning and this afternoon but we can't play the game at all now. UBISOFT HELP!!

So it's a video driver issue. Thanks Nvidia!!

The driver is up to date with the one that came out on Nov 9. Version 457.30

I submitted a ticket and gave them this post. Updates to come.

Ugh, I take it back. I closed the game to come back and put in the forum entry but when I started the game again it locked up at the title screen as before. Sorry gang, I'm at a loss on this one.

After looking at the error from event history I added C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games\Assassin's Creed Valhalla\ACValhalla_Plus.exe to Windows Defender Firewall. The game started right up with no issue. Hope this helps everyone.

This just started happening to me today. I've been playing it fine but with occasional crashes (usually while climbing mountains). Same as OP, no error message just a complete lockup at the logo.
