Symptoms

I've been trying to run the game with different versions of Proton, but only the native Linux version allows me to start the Launcher; But when I try to start the game I get the following error:

/home/user/snap/steam/common/.local/share/Steam/steamapps/common/Hearts of Iron IV/hoi4: error while loading shared libraries: libOpenGL.so.0: cannot open shared object file: No such file or directory

I've tried updating OpenGl but it says it is already updated. I'm using Ubuntu 24.04.

Reproduction

1. Launcher starts
2. Start the game with no mods
3. Get an error message (exit code 127) with the forementioned error

Start by reproducing the reported launch sequence on Ubuntu 24.04, using the Hearts of Iron IV executable path and the missing libOpenGL.so.0 error as the entry point. Review the supplied GPU, Mesa, kernel, and Steam runtime details, then determine whether the failure is environment-specific or requires a runtime change; done means documenting a confirmed cause and actionable resolution.
