Root Causes

1. Administrator Privilege Mismatch: Steam runs as an Administrator, but the game executable attempts to run with standard user privileges (or vice versa). Windows security architecture blocks the lower-privilege process from accessing the memory space of the higher-privilege process.
2. Third-Party Overlay Conflict: Overlays from software like Discord, NVIDIA GeForce Experience, or MSI Afterburner inject code into the game's rendering pipeline. If these injections fail or conflict with Steam's overlay, the Steam initialization check fails.
3. Antivirus/Windows Defender Interference: Security software may flag the steam_api.dll as suspicious (false positive) and quarantine it or block its network access, causing the initialization check to time out.
4. Corrupt Steam AppID: The steam_appid text file, which tells the game which Steam ID number to look for, may be missing or corrupt.
