Please describe your issue in as much detail as possible:
When trying to play competitive or any other official server, VAC error popup appears. Trusted launch in console is set to 1. I tried updating game, steam, verify files, restart PC, but nothing helped. Also happens on my laptop which is running AMD GPU. Problem started after the latest update.
Steps for reproducing this issue:
- Launch game
- Try to play on official servers
Same issue. This issue began on October 4, 2023, at 13:30 UTC.
System Information in gist.
Launch options
xrandr --output DP-4 --primary --mode 2560x1440 --scale-from 1920x1440 --rate 165 --pos 0x0; %command% -fullscreen -nojoy -vulkan; xrandr --output DP-4 --primary --mode 2560x1440 --transform none --rate 165 --pos 0x0
Things I have tried:
- Verify integrity of Game Files
- Restart Steam
- Go to Offline mode, exit Steam, Go to Online mode
- Reboot PC
- Restart router
- Remove all launch options
If I login with another account, I can play in Competitive modes (5vs5, Deathmatch, etc). If I switch back to my original account, I still get the same error.
If I login with another account, I can play in Competitive modes (5vs5, Deathmatch, etc).
I can confirm, that another account works. But even after switching to another account and then back, it doesn't work for the original account. Very strange.
If it helps while debugging the issue, here is Steam ID of the broken account: 76561198867803503
Same thing happened with me, since the 4th I've not been able to play MM. Tried a smurf account and it worked fine but my main won't work for some reason.
For some reason if one of my friends enters a DeathMatch and i click join friend it also works.
Also Switching to Windows works normally and i can play MM just fine.
My SteamID64 is 76561198019995663
1 - I've tried to uninstall the game 2 - Move the game to another drive 3 - steam --reset 4 - deleting config files 5 - fully updating the system(EndeavourOS) 6 - Using steam-runtime instead of steam-native
On a same boat here. Everything has been working since release of CS2 until on 4th I was unable to join matchmaking. I already tried: -verify integrity of game files -logged out of steam -uninstalled CS2 -multiple reboots -no VAC bans on account
Steam account ID: 76561198053290533
This is happening randomly in the middle of the game for me as well as a result I've recieived a week long cooldown.

@kisak-valve whats the ETA on this being fixed?
System info (Short:) OS: Arch Linux (up-to-date) GPU: GTX 1650 SUPER (driver: 535.113.01) CPU: Ryzen 5 3600 RAM: 16GB
Here my experience:
Whenever I try to start MM, I get the VAC error. no matter what mode. I have tried most of the already mentioned things to fix it, nothing helped.
However, I have noticed, when I am the lobby of a friend, and he tries to start a game, same VAC error, although when my friend is in a match (deathmatch) and I right-click join, I am able to play, without even getting kicked. And I can stay on the same server for multiple matches.
I am also having this problem, no solution has been found yet? I am on Linux too, it seems to be a problem with Linux
I've been wanting to play for several days, I've tried all the solutions and nothing can be solved, I hope something can be done
It would be more beneficial if, along with saying "same here," you also provide your System Information.
You may get your System information from Steam (Steam -> Help -> System Information) and post it in a gist.

Pardon me if I missed something and you've already tried it, but I can imagine this test scenario:
- Remove your steam installation (I believe it's not necessary to remove game files, i.e. to uninstall the game from steam library)
- Remove your
~/.local/share/Steam/userdataor~/.local/share/Steam/userdata/<your_profile_id>(I don't take any responsibility on the result; in my case it didn't break or change anything, I do believe the same data should appear after you log back into your account; also, I assume this directory may be different for you depending on your distro and your steam installation method) - Install steam again, log in to your account, check if the problem exists
My logic: if the problem exists only for some specific steam account - either something is wrong at the server side, or something is wrong at your local side.
P.S. Step 2 is the key, maybe steps 1 and 3 may be omitted.

Definitely a server-side problem. I tried on 3 computers. There is no chance, all of them have broken Steam install specifically for the same account.
Valve pls fix ❤️

Thank you for the input. I've attempted to uninstall CS:2 and Steam, as well as clean $HOME/.local/share/Steam/*, in an effort to start anew, but the problem still persists.
Is anyone else, who is unable to play, able to join a friend? (friend in deathmatch, right-click -> join)
(as mentioned in my last comment) I won't get kicked by VAC, which I find really weird and I would like to know if I'm the only one. it seems to work as normal even though I can't start any matchmaking by myself, nor can my friend in my lobby start a game with me.
The problem spontaneously resolved itself today, October 11, 2023, precisely one week after it initially occurred.
im revivving this issue as,...its back and im sad
According to the feedback from other contributors in this GitHub thread, it appears that the problem resolves itself naturally after a span of seven days.
Not working for me..
I've tried to reinstall both steam and CS itself, of course tried to verify game files, making sure i'm solely using runtime and making sure nothing else than the official softwares are being used. Not using Proton, making sure the official path is being used as well: /home/username/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive
Using the latest version of vulkan, Nvidia drivers, steam, even made sure to generate and use the offical locales (en.US- UTF-8).
Rebooted multiple times, removing all kind of background processes, solely running Steam & CS. Still not working.
I tried some weird work-arounds I found on random forum threads, like changing your avatar & profile name while running CS2 (Seems to have solved it for some people), also starting a local server, playing against bots seems to have solved it for some people. Not for me though.
I have literally tried everything I have found online, actively trying to debug for at least 15 hours straight today. Seems impossible.

i tried it on another pc and worked fine but its only on my account and on this pc that it does not work
Sup nerds - I was able to resolve my issue by doing the following.
sudo apt-get purge steam
sudo apt-get purge steam-launcher
cd ~/.local/share && rm -rf Steam
rm ~/.steampath
rm ~/.steampid
Then I followed the APT instructions at the following link: https://repo.steampowered.com/steam/
Having this issue as well. Tried every single fix I could find online but to no avail. Has been happening for around a week now. I tried with a second account and was able to queue into casual matches, so I assume it's an account based thing. https://gist.github.com/fortnider/49392f101ee0e7cf77a00e3de86a1b6b
@fortnider, the problem is linked to your account/PC. After 7 days from the initial occurrence, it should automatically resolve. You can play without any issues on another PC or using a different account during this period.
Same here with ArchLinux since two days ago. (SteamID: 76561197968560062)
Note: if i join game from a friend i can play.
Edit: after one week it has been solved.
