Reproduction

Start game, start prologue, games freezes and crashes after about 5 minutes of playtime.

Comment: the log file has appid 1317860, in steam the URL shows 1293860 for the Prologue, full game ID in Steam URL is: 780310
I've tried both the demo and the Prologue, they behave the same.

Start by reproducing the crash with the Steam demo or Prologue using Proton 5.13-2 and 5.0-10, then inspect the attached steam-1317860 and multipart steam-1293860 logs. Done means identifying the cause of the freeze and crash after roughly five minutes and confirming a fix against the reported reproduction steps.
