Cyberpunk 2077 has flatlined (Solved)

[ThornRage]

After the launcher comes up and I select Play, I wait about 1 minute and then a popup comes up saying "Whoa! Cyberpunk 2077 has flatlined."

I am unmodded and have reinstalled twice. I have verified files. None of this happened until the latest patch.

This is what is in the report.txt file:

I have 546.29 (rel 12/4/23) which is the latest.
Thanks though.

[The Tempted Man]

you have neverst visual studio? It helped in my case when I had crashes

[MariusGaius5]

I had the same problem. But if your Graphic Driver is up to date it might be STEAM overlay. Try turning that off. If those 2 things don't fix it... sorry. Good luck Thorn.

[NetshadeX]

Yeah I'd say try to shut down anything you may have running in the background. Other game launchers, fps counters etc.. Also if anything is overclocked, try running stock clocks. I remember Ghost Recon Breakpoint crashing on me all the time before I figured out it was the overclock on my CPU it didn't like.

[hagathina]

I'm in the same boat, only my game is on GOG. Nobody there has responded to my query, so I've posted here, too. I've tried the suggestions I've seen here but nothing works.

The frustrating thing is that the game worked for a bout an hour. I exited to see if I could find some tweaks and when I went back in the Flatline crash started and I've not got the game going since.

Bummer, since I've been looking for ward to it for ages.

This game is indeed very picky about overclocking and stability over all. This includes GPUs that have a factory OC.

Even with a stable overclock that the game likes it can lead to logic errors causing cars to spawn in the air and other amusing but not really game breaking bugs.

Maybe try this https://appuals.com/cyberpunk-2077-not-launching/

I learned I have to disable iolo System Mechanic and then enable after I get the game started

Finally got it to work! Such a hassle, i guess to where i had to uninstall/reinstall, my firewall had 4 different versions of it, so i removed the others, allowed on both, public/private, ran the game as Admin an voila. The above post helped.

Yeah, could you specify? I'm also having this issue since 2.1 and would very much like a resolution.

It flatlined on my PC, and then I tried the following.

1. I restarted the PC. It didn't work.
2. I turned off the AV. It didn't work.
3. I uninstalled the AV. It didn't work.
4. I overclocked CPU. It didn't work.
5. I used the highest settings for GPU. It didn't work.
6. I tried launching the game with admin. It didn't work.
7. I closed other programs. It didn't work.
8. I disabled several services in Task Manager. It didn't work.
9. I checked the integrity of the game files. It didn't work.
10. I cleaned my C Drive. It didn't work.


11. I updated drivers using the GeForce program. It worked.
