While I understand newer kernel versions won't necessarily affect this issue (assuming vulkan API calls and whatnot) I will state that I have attempted to launch the game on every kernel update since I added this github issue (and on every proton version that I have originally attached logs for) and the issue persists.
Fixed by game devs upstream "Fixed the issue causing the game to crash on Linux (both SteamDeck and desktop Linux) when the game tries and fails to access Braze." Closing this issue now.
