I'm not sure what happened between yesterday and today, but I suddenly can't run Hunt. I tried loading up a couple other games I have installed and Half Life 1 launches, The Mound does not I get an error (this may be due to the demo being over I think) but also Valheim won't launch at all.

Hunt loads the splash image for anti-cheat, then the full screen goes black, I then get Hunt's red cursor. A few seconds later I get a pop-up that says Steam isn't responding with the options to either Force Quit or Wait (which does nothing, the popup immediately returns). My machine is up to date on Ubuntu 24.04, Steam is up to date, and Hunt is up to date (I was playing it yesterday with no issues).

I've been running it with Proton Experimental and no launch options. 

Thank you guys for your help. My system details are below.
