Well it looks like its a deliberate crash by blizzards anti-tamper engine:

Diablo IV (2344520)

opened 05:54PM - 25 Oct 23 UTC

Game compatibility - Unofficial Regression

# Compatibility Report - Name of the game with compatibility issues: Diablo IV … - Steam AppID of the game: 2344520 ## System Information Steam Deck - latest full 3.4.x release (NOT 3.5.1 preview) - Proton version: Proton Experimental - set by Valve in Game Properties (as of 10/25/2023) ## I confirm: - [X] that I haven't found an existing compatibility report for this game. - [X] that I have checked whether there are updates for my system available. ## Symptoms: Diablo IV fails to reconnect to Blizzard servers after using the sleep/wake function. I'm not sure if this is a game issue or Proton, but the sleep/wake function on Playstation and Xbox work, so I'm reporting here for awareness. ## Reproduction Launch Diablo IV on Steam Deck Connect to Blizzard Servers, load into game after character select Put Steam Deck to Sleep Wake Steam Deck back up Your character is still in the world, with "Connecting to Diablo IV Servers" in the upper left corner Game will fail to connect to Diablo IV servers, returns player to main menu Game fails to connect to Diablo IV servers in main menu, application exits to desktop Expected behavior is for the game to successfully reconnect to Blizzard servers and allow player to resume gameplay. Note that in a normal scenario (e.g. on Playstation and Xbox), any server or client related hotfixes or patches will result in showing the player an error and exit the application. This is normal behavior when there is a server & client mismatch. The issue I am describing here is NOT a result of server/client mismatch. This issue is reproducible 100% of the time, even when using the sleep function very briefly (e.g. under 2 minutes).

If thats true, last time I spent money on blizzard products, back to POE 2 I guess…
