Symptoms

After playing the game for a relatively short amount of time, the game freezes and starts having audio played in a loop.
What's worse, the entire system freezes, requiring a hard system reboot.
Around the time it occurs, I imagine this access violation error is thrown in the log:

Reproduction

1. Launch the game
2. Play the game for about ~30 minutes or less
   (when it specifically happens is unknown but it doesn't take long to trigger in normal gameplay)
   (Usually happens at the player's camp, from what I've experienced)

Begin with the attached steam-1313140.log and the listed reproduction steps; compare the access-violation entries with the reported system, driver, kernel, and Proton details. Done means the game no longer freezes the system or loops audio during roughly 30 minutes of normal play, especially at the player's camp, on the reported setup.
