Bug Report: Crash Caused by EOS Initialization (EOS_UserInfo_BestDisplayName_Release)

[Larthen]

Version

7 Days to Die v1.16.4 (A21 / V2.0) – Steam

Platform

Windows

Game Version
7 Days to Die v1.16.4 (A21 / V2.0) – Steam

System Info
OS: Windows 11 x64

CPU: AMD Ryzen

GPU: AMD Radeon RX 6650 XT

GPU Driver: 32.0.21013.1000

Antivirus: Kaspersky (crash reproduced with it fully disabled)

Steam Launch Options tested: -noeos -noeac -force-d3d11 -nolog

Summary of the Issue
The game crashes during startup while initializing Epic Online Services (EOS), even when EOS-related launch options are set. The crash occurs inside:


EOS_UserInfo_BestDisplayName_Release
EOS_Mercury_Tick
EOSSDK-Win64-Shipping.dll
Disabling antivirus and using -noeos or -noeac does not prevent the crash.

Steps to Reproduce
Launch the game without EAC (via Steam)

Keep platform.cfg set to:

platform = Steam
crossplatform = EOS
Game crashes before main menu loads

Tested Workarounds
Tried and failed:
-noeos launch flag (EOS still initializes and crashes)

Disabling antivirus and overlays

Installing Epic Games Launcher (no change)

Reinstalling the game and clearing temp/cache folders

Successfully fixed by:
Setting:

crossplatform = ""
in platform.cfg (Steam-only networking).
This prevents EOS from initializing, and the game launches and runs perfectly.

Side Effects
Disabling EOS changes player ID from EOS_... to Steam_..., which may affect access to prior saves or multiplayer if the server uses crossplay authentication.

Request
Please investigate and patch the crash triggered in EOS_UserInfo_BestDisplayName_Release

Same issue. I went into platforms.xml and removed EOS from crossplatform= and it loaded fine.

This all seems to be caused by a temporary outage on Epic's side, FYI
