[SOLVED] Steam/Proton fails with status c000012f across multiple games

wine: could not load kernel32.dll, status c000012f
pid 27771 != 27770, skipping destruction (fork without exec?)

This happens across multiple (but not all games. I have tried cleanly uninstalling and then reinstalling Proton.

Moving the games from the NTFS drive to XFS does not help.

The affected games:
* Uncharted
* Tomb Raider
* Mass Effect
* The Talos Principle 2
* Myst
* Firmament
* Elite Dangerous

unaffected games:
* Stellar Blade demo
* Everspace 2
* Exo one
* Obduction
* Outer Wilds
* GRIP

Full Steam output: https://paste.c-net.org/WhaleDoozy
I serially tested all games in that steam session.

I was unable to find anything useful online.

Why I run Arch? To "BTW I run Arch" the guy one grade younger.
And to let my siblings and cousins laugh at Arsch Linux...

There are often issues with funky vulkan layers and/or older xorg drivers (if installed, try to get rid of xf86-video-amdgpu), is something wonky here? Though I'd expect everything else to fail in that case but just for verifying.

vulkaninfo --summary

and a xorg log would be nice.

You mention a NTFS drive, did you configure that properly like mentioned in: https://github.com/ValveSoftware/Proton … ead-errors , so that your Proton prefixes land on a POSIX filesystem  and did you ensure those are deleted as well when "cleanly uninstalling"?

That did the Trick, thank you very much!
The cleanly uninstalling was more getting rid of the clusterfuck when removing one of multiple proton versions, it always breaks the others.

I also had xf86-video-amdgpu installed for some reason. whoops.
