I am unable to play CK3, it crashes immediately after I press the button to launch the game. I have tried using proton, downgrading the game, and it still does not work.

I know of two possible causes to this problem on Linux.
One is if you've used the Snap or Flatpack installs of Steam, which do not work well with our games. You need to use the native Linux client from Valve:
http://store.steampowered.com/about/
"Install Steam Now"
The other is an issue with Steam when you have Proton installed; Steam sometimes thinks you have the game on WIndows not Linux so installs the wrong version. If you see ck3.exe (ie the Windows executable) in your Steam folder for this game, that is the problem!
You can get past that as described here:

All the best!

I have the same behavior since 1.16.1 patch (1.16.0 worked without any issue).
I did have Steam native client and no windows version installed :
Also note there is no crash log, nor any message when launching the game in command line :

/steamapps/common/Crusader Kings III$Odd to not get any error at all. What distro is this? If you revert to 1.16.0 in the Steam betas tab, does that still work?
Please attach here your Documents/Paradox Interactive/Crusader Kings III/pdx_settings.txt .
From your Documents/Paradox Interactive/Crusader Kings III/logs/ folder, attach here system.log , error.log
Also in Steam please click on Steam-Help-System Info, and paste everything there into a text file and attach that here.
I am on Debian 13 (Trixie), strange that something is broken because this release is soft locked (feature change halted) since a month for a future official release.
But no, even the 1.16.0 does not work (exact same behavior) so might be a change in the distro.
Please find attached :
.local/share/Paradox Interactive/Crusader Kings III/pdx_settings.txt
.local/share/Paradox Interactive/Crusader Kings III/logs/error.log
But last logs only refer to error from additional game rules added by mods, but in all my last tests (1.16.1, 1.16.2 and 1.16.0) I did not load any mods.
I also added .local/share/Paradox Interactive/Crusader Kings III/logs/setup.log because last log entry seems to be incomplete :
Code:

[13:59:30][W][provincetemplate.cpp:160.local/share/Paradox Interactive/Crusader Kings III/logs/system.log is empty, so I ignored it.

Sorry, I see no reason for this problem in those files at all. You could try disabling Vsync and capping the refresh rate to 60 in the launcher-game settings tab, but I frankly doubt that will help.
Do you have access to any Linux support resources that might point you to OS logs that could have recorded why the executable is failing without apparent error?

I did not find any relevant indication in OS logs.
But in my most recent test, the game started with this additional prompt (launching from command line) :

IPC function call IClientUserStats::GetAchievementDisplayAttribute took too long: 62 msecPresumably that is due to not being launched from Steam, as that is where the achievements are stored. So nothing to do with your problem.
I don't really have anything else to suggest, I am sorry! The fact that a game version that used to work no longer does points to some local problem, but we see nothing to indicate even the general area of the issue.
Do you happen to have access to a Ubuntu installation to check it works okay there?

I am not sure, because I launch the game with steam launched, and they successfully communicate (there are other specific messages if steam is not found).
It seems that know I can reliably launch the game from command line successfully.
But it still crash when launching from steam.
I agree it seem to be a local problem, probably linked to the recent change of my linux distro (debian 13 trixie) interacting with the game and steam.
I did not expect help now, I just wait for the distro to stabilize, and letting you (and any other user in same case) know the evolution of my tests.
Unfortunately no Ubuntu installation available, but I have other Debian on previous version (debian 12 bookworm), I will check on it.

I was having issues too starting CK3, this time on Archlinux, after a year without playing. I managed to fix the issue doing two things:
* I changed the start command to: "%command% --ozone-platform-hint=x11"
* I had set SDL_VIDEODRIVER="x11,wayland", which I had to unset.
With these two changes, I successfully managed to launch CK3.
* I changed the start command to: "%command% --ozone-platform-hint=x11"
* I had set SDL_VIDEODRIVER="x11,wayland", which I had to unset.
With these two changes, I successfully managed to launch CK3.
I have finally made tests to find usable linux log.
Note that I tested changes proposed by Med1980 and did not solve anything for me.
I launch the game from steam, launcher is displayed, I start the game from launcher successfully, the crash occur shortly after the music starts and before the menu is displayed.
When I start game from command line (without launcher : steamapps/common/Crusader Kings III$ ./binaries/ck3 or with launcher :
steamapps/common/Crusader Kings III$ ./launcher/dowser) I have following logs
So the problem seems to came from steam handling.

No real idea what this means or why it only occurs when you run the game from Steam! I assume your Glib is up to date?
