Game won't even launch.

[LaZoR Bear]

Game won't launch, reinstalled the game, verified game files, reinstalled Ubisoft Connect, launched from Ubisoft Connect, validated drivers.

I'm on a 5600x with a 3080. Anyone got anything I haven't tried?

I manage to get it to start, I don't know how, I kept repeating the same steps again and again. When I got in game, I changed the graphic settings and it required a restart and now I can't get it to launch again. What a ♥♥♥♥ show.

I been getting the AVX2 fatal error but other games that use AVX2 or similar i can run no issues. Trying to find workaround will shout if i find a solution.

You need to change from Steam Client Beta to Stable Version, that helped me

for 1st time try to have ubi app on before you press play

The thing that worked for me (and not on the first try) was to deactivate my wifi adapter completely in the network settings. I had seen that tip in another thread, tried it and it didn't work, but after turning it on and off again and rebooting my pc it worked. Hope it can help someone that doesn't rely on wifi for the internet.

I still haven’t been able to play the game either. Launch it, splash screen, crashes back to hitting play again

oh, finally a topic with "cant start the game" ... took you crash peoples with unoptimized rigs a while to pop up. ... or ya posts got eaten by the AC shadow anti and pro crowds.

i was really wondering when topics like this pop finally up.
like, i was already wondering if ubisoft managed what many triple A devs cant do nowadays, aka testing a wide range of rigs if the game runs or not on it without problems lol xD.

I FOUND A FIX you need to diable the internet and the wifi then start the game

yeap, same thing here, tried everything but the same results... Opened a ubi ticket, bot only got default answers

[superlloyd]

That's a weird reason for a game not be able to start.
I think I read someone else having an issue with some memory anti cheat protection or something. I think...

If your game closes right after launching and nothing shows up, it could be crashing because of a Windows file called `ntdll.dll`.

🔎 How to check:

1. Press Win + R , type eventvwr.msc and hit Enter
   
2. Go to Windows Logs > Application
   
3. Look for errors called Application Error
   
4. Click one and see if it says something like:
   

    Faulting module: ntdll.dll
    Exception code: 0xc0000005
    Game: ACShadows.exe 
   

(I'm having this issue too. I've been talking to Ubi support, and if I find out anything new, I'll let you guys know)

Damn.. this is the big Windows DLL with almost all system calls...

And 0xc0000005 means access violation. I.e. some kind of C++ buffer overrun or something. Good luck with that!

So I followed your steps and I found a similar error in my event log. tied to Event 1002. I searched for that and found a random forum post stating that it was tied to screen display sacaling set to 125%. I just happened to have my display scaled to 125% so I knocked it down to 100%, rebooted my system, and now the game launches!

Great work!

It's sad the game crash from some system settings like that. Cant blame Unreal5, since they use Ubisoft Anvil... But great that you found out a fix for you :)
