Horizon Forbidden West accumulates graphics/audio errors and then crashes

Your system information

• Steam client version (build number or date): 2024-11-05
• Distribution (e.g. Ubuntu): Gentoo Linux
• Opted into Steam client beta?: Yes (but reverted it because the beta client has no in-game sound)
• Have you checked for system updates?: Yes
• Steam Logs: attached steam-logs.tar.gz
• GPU: AMD (Radeon RX 5700 XT)

Please describe your issue in as much detail as possible:

Since last week's update the game rapidly accumulates the following errors:

• tall grass proliferates in environments where it shouldn't be (ie, covers an entire hillside where normally it's just a couple isolated clumps, or fills an entire settlement)
• the in-game map won't load, showing instead a black screen (even though hovering the mouse around the screen causes the sound of the map as if the map is there)
• certain audio channels stop: music, dialogue with NPCs, most environmental sound, most combat sounds; but not the sounds of footsteps.
• the "compiling shaders" black screen starts interrupting gameplay
• certain campfires (which are the quick-save points) stop working
• clothes start showing scrambled textures
• at this point, I have to save and restart the game, because it freezes not long after.

Steps for reproducing this issue:

1. steam client auto-updates from last week's update
2. play the game for maybe 20 minutes
3. start noticing problems

I did not have any of these problems after the game updated to its current version over the summer. This only started happening after the Steam client updated last week. I am using GE-Proton-9.{11,15,19}, but that doesn't seem to have any effect.
