If you're using XMP try disabling it.

i see like 20 different "THIS IS THE SOLUTION" reasons..

who can tell me what's most likely the case?

The problem is likely your CPU, 13900k and 14900k CPUs have been having a lot of problems lately because of the way motherboard venders don't respect the safe limits for current and power. You need to go into your BIOS and hand set the Max Amps and Max Watts to Intel suggested safe levels because currently they are set way too high. Just Google "13900k 14990k problems" and you find all kinds of websites and YouTube video talking about it and how to fix it

That's an ASUS product if I remember right so ASUS likely has a BIOS update by now that will fix the problems caused by their older BIOS

Here is something Sony/Nixxes has been posting in the FAQ for all their recent games but the information applies to all games and crashing issues with the 13900k/14900k CPUs

Crashes on Intel 13th and 14th generation CPUs

If you are experiencing game crashes on 13th and 14th generation Intel CPUs, this may be related to hardware configuration settings.

Intel recommends using 'Intel Default Settings', while various motherboards may apply different settings by default.

You can find details on Intels recommendations in the articles below:

Thanks guys!

Have you overclock your GPU? I had, and odyssey frequently crashed and Cyberpunk too, but other games were perfectly stable. but after lowering my OC because of Cyberpunk, i notished that odyssey also stopped crashing. So if you have overclock your graphics card do try lowering it, it might just stop the game from crashing.

It crashed 2–3 times during my 146h play through so far. I submitted the reports via the Ubisoft client. The other games are pretty stable. Also, it stuck on exiting a lot and I have to manually restart the PC (the same with Origins). Not a big deal but very annoying. My GPU is factory OC (not by me) and I am using the XMP profile for the RAM. The CPU is a bit old i8700k (so this is probably not related to the instability of 13 and 14-gen).

I dont need to overclock with my setup, so no i didnt

Go into the Connect App and in the Settings turn off the Overlay and Cloud Saves and that will likely fix your shutdown problems. It's mainly caused by the wonky net code used for Cloud Saves. It tries to send a save to the cloud during shutdown and gets stuck

Thanks. Already did that (I saw a post at Reddit) and it worked. However, the next day when started the game the client wanted me to turn on the in-game overlay, which I did and it stuck again. I have disabled it again and turned off the message from the client that wanted me to turn it on again. So probably these both should be disabled for the fix to work properly. And still Ubisoft didn't fix it for all these years is really embarrassing. Probably this is not their priority.

Well technically it's not the game itself that is the problem it's the Connect App. I've had Cloud Saves disable since December 2020 because it was causing so many crashes in Valhalla and while it didn't stop the crashes because there are 2 or 3 things that cause crashing in that game it did cut the number of crashes in half

Even if you delete the game the saves stay on your drive and are safe as long as you don't format the drive and re-install Windows. All you have to do is back up the C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\savegames folder and all your saves of all your Ubisoft games you've played will be in there. I have saves on my computer going back to 2017 when I had a completely different computer. Plus I image my C: drive every week so it's also backed up there

Nice. I image my C:\ drive as well with Macrium Reflect at least twice a month. Never been disappointed so far with it.

Not my solution, found it on Reddit, but it worked for me after a month of pulling hair and teeth out with frustration...."Boot the game and then task manager, right click AC Odyssey, click details, right click the Ac Odyssey.exe it highlights in details, click set affinity, and checkmark each box for however many cores your CPU has."

After doing this, I have yet to crash. Hope this made sense, and hopefully it helps some people out.
