If you are having issues with Steam Proton and accessing the legacy native Linux version of ARK, you can try a few things. First, make sure that you have the latest version of Steam Proton installed. You can do this by opening Steam, going to the "Library" tab, and then selecting "Tools".
From there, find "Steam Play for all other games" and update it to the latest version.
If that doesn't work, try adding the following launch options to your ARK game in Steam: -force-d3d9
-force-feature-level-11-0
-force-feature-level-10-1
-force-feature-level-10-0
These launch options have been known to help with some Steam Proton issues.
If you are still having issues, you can try accessing the legacy native Linux version of ARK. To do this, right-click on the ARK game in your Steam Library and select "Properties".
From there, go to the "BETAS" tab and select "legacylinux" from the drop-down menu. This will give you access to the legacy Linux version
