Arch Linux Launcher Won't Start

[snifflywhale]

Yesterday I found Crusader Kings II no longer launches through Steam, and subsequently discovered that I cannot get it working at all. I've tried a full reinstall deleting both Crusader Kings II's Steam folder as well as ~/.paradoxinteractive.

I'm using Linux version 5.5.3, graphics driver is mesa 19.3.4-1. My PC has an Intel Skylake i5, 16GB RAM, and an AMD RX580 graphics card.

Attempting to launch the ck2 binary directly from terminal gives

Video Driver 0 = x11
terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
fish: “./ck2” terminated by signal SIGABRT (Abort)

I tried running strace ./ck2 and it produced the attached output. I don't know how helpful it will be.

When did it last work? IOW do you know what change or update seemed to break it?

If it could have been the Mesa driver you might try the current ones, which are 20.something now.


That aside we have no real clue in those files what the problem is! Anything in the error.log or exceptions.log files for the game?

I downgraded mesa to 19.3.3-1 and it worked. Thank you!
