I'm running Pop! OS 22.04, and encountering a particularly annoying issue; I boot up Steam, select KC:D, click "start", and then... nothing. I get a "launching" notification in the list tab, but nothing ever actually launches- but no error messages ever pop up, either. Changing the version of Proton doesn't help; I don't even get the usual "Vulkan shaders" popup that other games give. I've even tried redownloading it, but there's no difference.

Anyone else had (and more importantly, fixed) the same issue?
