Hello @kamikazechaser, for reference, the attached minidump is a SIGSEGV in libc.so.6 coming from librendersystemvulkan.so.

Possible duplicate of #2400.

[kamikazechaser]

yes, behavior seems to be consistent. I have seen similar reports on the other issue repo:

• https://github.com/ValveSoftware/Dota2-Gameplay/issues/11140
• https://github.com/ValveSoftware/Dota2-Gameplay/issues/11099

^ and many more. Not sure if related.

Game crashes after the start, when a notification("Access steam community while playing") Regardless of when it appears (during the intro video or after loading the menu). Crash during the appearance of this notification. Before the summer update everything worked fine

Also tried to use Steam Beta Client and other Compatibility Runtimes (Steam Linux Runtime/Sniper (Including previous_branch, beta), Proton) to no avail.

Moving my comment to this issue: https://github.com/ValveSoftware/Dota-2/issues/2285#issuecomment-1703729199. Have you guys find a fix yet? What else can I do to help? Thanks.

[kamikazechaser]

No luck on my end yet.

[tfhavingfun]

Should also mentiion that if I set compatibility tool to Proton Experimental, Dota 2 launches into its main menu, but crashes after a while.

[tfhavingfun]

It's resolved for me. What I did is just rm -rf ~/.local/share/Steam ~/.steam and run steam-runtime --reset (probably not necessary) and of course reinstall Dota2.

[kamikazechaser]

Glad it worked for you. I might try it out later. Not really an ideal solution though if the game has to be reinstalled. I suspect the issue is probably the runtime. From what I have gathered, dota2 runs in a container environment shipped with its own dependencies.

Yeah. My new install only brings steam linux runtime - sniper which is the newest version. Used to have other versions installed on my system and I suspect Steam got confused and used the wrong version for Dota2.

From https://github.com/ValveSoftware/Dota-2/issues/2285#issuecomment-1703729199, https://gist.github.com/tfhavingfun/858f1a1d207c628330c5fdc66ffc5f39#file-gistfile1-txt-L39 is evidence that Steam was running Dota 2 with Steam Linux Runtime - Sniper before you nuked your Steam install. That's the current intended runtime configuration.

Reinstalling does fix it. But a far from ideal solution for those with bandwidth constraints.
