Almost every time dota getting major update - i'm unable to launch it or play a game without crashes Now I have this when trying to launch dota.sh:

CS2 is working, but when game is losing focus - it's crashing. It's strange, cause when CS2 released - Dota2 had similar issues as CS2. (Sound problems, wayland/x11, SDL, etc.. it was the same)

Manjaro, can't start either. Window opens up, I see Dota logo, mouse changes style like it should, logo disappears, black screen for a few seconds, window closes. Checked for updates, verified files. Restarted Steam, restarted system, removed launch options, tried with gamescope. Tried few other games, they works.

Yesterday it was working, did nothing on my end.

Was able to launch by restarting Steam and deleting shadercache /home/username/.local/share/Steam/steamapps/common/dota 2 beta/game/dota/shadercache/ To launch again I need to restart steam again and clear cache again and do not use launch options.

Also worked for me. What is this file for? And I have launch options, like mangohud, gamemode, -map dota, etc...

Shaders, they determine how skills and effects and other stuff looks. Usually it's better to not delete them, because their calculation cause micro-stutters first time they appear on the screen. But sometimes they glitch (which normally should not happen) like this time I guess and it's a reason to try to make them generate from scratch.

I played two games and watched live game, it was ok.

game is working fine right now, but crashing sometimes when changing volume level or alt-tabing

For me it's still deleting shaders and restarting steam.

Fixed for me with 7.35c update

Hello, I'm running 6.8.9-arch1-2 .

Dota 2 won't launch since yesterday with the same error messages as described above. I've tried running in XFCE4 with X, and in wayland with sway. Tried both the native and flatpak Steam apps. Same issue persists.

Starting steam with steam %U STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 does not fix the issue (suggested here https://github.com/ValveSoftware/Dota-2/issues/1705)

I get the following messages every time when running either the above command or starting Dota 2 from the Steam UI. Has anyone got an alternative solution to the issue?

The only way to make the game launch is to force with Proton-Experimental compatibility tool. However, doing this won't allow me play online as it triggers "Valve Anti Cheat was unable to verify your system is secure"

Just had the same issue with 6.8.9, downgraded to 6.8.4 and it works now. I used the guide to downgrade from https://arcolinux.com/how-to-downgrade-a-linux-kernel/ The AUR package downgrade is used there.
