Cyberpunk 2077 PC Crash Issues

[Souls-Bird]

Hi guys, my game also crashes at launch, when I hit "play" from the Red launcher.... BUT I have latest Windows Pro version 20H2 !!!

Here is my setup :

Steam version
Windows 10 Pro Version 20H2, build 19042.685
CPU Intel Core i5-4670K
GPU MSI GeForce GTX 750 Ti GAMING
8Go RAM
HDD disk usage

I got the EXCEPTION_ACCESS_VIOLATION (0xC0000005) error message...

It was a bit tough for me too, had to mess around with the search function in the program I was using. Perhaps someone can recommend a good Hexademical editor and some simple step by step directions.

https://www.nexusmods.com/cyberpunk2077/mods/34?tab=files instead just download the predone version simply rename it to cyberpunk2077 and voila place it in the directory and save your original exe incase.

Confirm exe file work good. Confirm exe file work good. I pass bar and chair.

Use HxD: https://mh-nexus.de/en/hxd/

Menu Search -> Find

Then look in the tab Hex-values

Game crashing on old CPUs: possible fix



If you happen to have an old CPU you maybe having this crash:



Expression: EXCEPTION_ILLEGAL_INSTRUCTION (0xC000001D)



The game is trying to use a feature you don’t have: AVX.



At the beginning playing corpo when you sit it crashes. A possible temporal solution while they fix this issue is to remove this part of code:



Edit Cyberpunk2077.exe with a hexadecimal editor and search for

554881ECA00000000F2970E8

Change the first byte to C3 (return from the function):

C34881ECA00000000F2970E8



Please note this fix is extremely simplistic and naïve. Moreover, it could crash the game later. This change seems to fix this crash and you can continue playing the game. I have only tested a few minutes more.



FAQ: Why are they using AVX?

They are not doing it on purpose, it is probably the default configuration of the compiler.

This 100% worked for me!! I had also cleared the game's cache, but this was a night and day difference!!
The game FULLY WORKS now!! (well, for now!)

 

[shadowskings]

Holy smokes this works for the AVX related specific prologue crashes. Never used a hexadecimal editor before so it was a bit tricky, but thanks! How the dickens did you figure this out? I hope they can release a real fix soon. If we run into trouble, how hard is it to put these values back to normal, and will they fix themselves if we validate files?

THANK YOU THANK YOU IT WORKED

DL- HERE https://mh-nexus.de/en/downloads.php?product=HxD20

ONCE DL OPEN FILE9CP2077 ) THROUGH HXD , AND USE THE SEARC HEX

[Adderall_Paul]

Well i've fixed my game and spread the word as much! Time for me to enjoy my CORPO Ghost In the Shell V Playthrough

 

[Cryoto]

Does this game work for any AMD CPUs at all?

 

[Evaldas85]

https://www.nexusmods.com/cyberpunk2077/mods/34?tab=files instead just download the predone version simply rename it to cyberpunk2077 and voila place it in the directory and save your original exe incase.

I opened Cyberpunk2077.exe in HxD Hexadecimal editor and cannot find 554881ECA00000000F2970E8

Also, how do you see "Expression: EXCEPTION_ILLEGAL_INSTRUCTION (0xC000001D)"?

This fixes the crash we get on older i7s and Xeons that lack AVX instructions. CTD happens when exiting the bar or sitting on the chair in the corpo intro.

1. Someone released an assembly code edit of the .exe on Nexus. Get that here: https://www.nexusmods.com/cyberpunk2077/mods/34?tab=description
2. Delete your CACHE folder here at C:\Users\XXXXXXX\AppData\Local\CD Projekt Red\Cyberpunk 2077
3. Launch the provided .exe; Now the size of the provided .exe is the same in bytes as the original. This leads me to think that a line was changed in the code and no malicious code was added. Use at your own risk. The alternative would be to hex edit the .exe yourself. there are posts about that.

This fixes it on my X5675. I run the .exe provided after deleting cache. It wouldn't even load the cinematic without removing cache.

FYI CDPR is working on a fix as mentioned on the CDPR forums

 

[br3adfish]

Here's my guide on how I fixed it using the nexus mod combined with flushing the cache:

I run a X5675 Xeon that does not support AVX. So far so good!

Too bad haha, seems they dont like inofficial fixes.

Damn I didn´t read about this exe fix, I managed to play with a nomad lifepath with this; https://steamcommunity.com/app/1091500/discussions/0/2988665684325649357/?ctp=11

So started as Nomad - when you enter Night City and there is a bunch of cutscenes - when it goes to load it looks like I am in a car and the game crashes every single time. Tried lowering gfx settings but didnt make a difference. I'm not using the GOG launcher (but disabled overlay as some suggested). Disabled steam overlay too.

Tried a new game as corpo - as i enter the office and hit "sit down" it also crashes. Not tried street kid yet but assuming there will be a point of crash there too.

Any suggestions?

EDIT to update system specs:
OS: Windows 10 10.0.19041 Build 19041
CPU: Intel i7 960 @ 3.2Ghz
Memory: 16GB
GPU: AMD Radeon R9 390
Running on HDD (SSD out of space)

I know it is an old system.. but so far I've never had an issue playing anything. Seems a tonne of people have the exact same issue I have - crashing at the "exact" same spot (Sitting down in corpo start, or entry to city in nomad and getting a "glimps" of sitting in a car I think).

Appreciate anything to get this working - not a complain post but "can you help me" post I know it has tonnes of bugs and I need an upgrade

Have this same issue. So far, nothing has helped

Well you can hex edit your exe yourself. There's a guide how.

I used the nexusmods exe which does the same, works like a charm on my Xeon W3690

Holy Crap! It worked! How on earth did you figure this out?
