Just adding that the crash (program exit to desktop) occurs with Proton 7.0 as well. There is another place where a crash occurs sometime after the one mentioned already. Loading (saved game) near the location and trying again can get through it. But player does need to make saves frequently..
Side note: fonts look better in Proton 7.0, earlier there was odd spacing between characters.

Compatibility Report
System Information
I confirm:
Symptoms
While playing there is a scene where game closes unexpectedly (crash).
I did get through that scene once, which might indicate a timing issue of some kind.
Reproduction
Play the game normally. The location of crash needs around one hour of playing to reach.
