Explanation

Issue Summary
When attempting to launch Deep Rock Galactic: Rogue Core via Steam on Windows 11, the application fails to start properly and returns CreateProcess() system errors.

Initially, the process failed with code 11c7. After disabling Smart App Control (SAC) and security software, launching the game results in an immediate crash during startup, followed by a new pop-up error: CreateProcess() returned 2e4 (ERROR_ELEVATION_REQUIRED).

Additionally, when running with administrative privileges, Steam prompts a background dialog warning about unexpected custom arguments (RogueCore -serverlist=serverlist.ghostship.dk RogueCore) before closing abruptly.

System Information
OS: Windows 11
Platform: Steam
Game: Deep Rock Galactic: Rogue Core

Error Details & Error Messages

1. Initial Launch Error (Smart App Control Enabled)
   Error Message:

   Couldn't start:
   "C:\Program Files (x86)\Steam\steamapps\common\Deep Rock Galactic RogueCore\RogueCore\Binaries\Win64\RogueCore-Win64-Shipping.exe" RogueCore -serverlist=serverlist.ghostship.dk RogueCore
   CreateProcess() returned 11c7.

2. Secondary Error (After Disabling Smart App Control / Security Software)
   Error Message:

   Couldn't start:
   "C:\Program Files (x86)\Steam\steamapps\common\Deep Rock Galactic RogueCore\RogueCore\Binaries\Win64\RogueCore-Win64-Shipping.exe" RogueCore -serverlist=serverlist.ghostship.dk RogueCore
   CreateProcess() returned 2e4.

   Behavior: The game crashes immediately upon launch, and the 2e4 (ERROR_ELEVATION_REQUIRED) pop-up appears right after.

3. Custom Launch Arguments Prompt (When Executed as Admin)

   Behavior: Running the binary as Administrator triggers Steam to display the following prompt in the background before the process terminates:
   Plaintext

   "Deep Rock Galactic: Rogue Core is attempting to launch with the optional parameters below:

   RogueCore -serverlist=serverlist.ghostship.dk RogueCore"

Troubleshooting Steps Already Attempted

Disabled Smart App Control & Security Software:

Disabled Windows 11 Smart App Control (SAC) and added the game installation folder (.../steamapps/common/Deep Rock Galactic RogueCore) to Windows Defender exceptions. (Resulted in error changing from 11c7 to 2e4).

Steam File Verification:

Executed "Verify integrity of game files" through Steam (all files passed validation, but issue persists).

Cleared Launch Options:

Cleared all custom arguments under Steam Library > Properties > General > Launch Options.

Tested forcing DirectX parameters (-dx11 and -dx12).

Local Data & Cache Reset:

Renamed/deleted local user data and configuration cache in %localappdata%.

Privilege Adjustments:

Toggled "Run as Administrator" on RogueCore-Win64-Shipping.exe and Steam.exe.

Expected vs. Actual Result

Expected Result: The game launches normally without failing CreateProcess() or passing malformed duplicate command-line arguments (RogueCore -serverlist=serverlist.ghostship.dk RogueCore).

Actual Result: The launch sequence halts with CreateProcess() returned 2e4 (or 11c7 prior to disabling SAC) or crashes silently after prompting the custom arguments dialog.
