This error occurs when the Steam API isn't properly linked. Solutions:
The WriteMiniDump function is a part of the Steam API's ISteamUtils interface, which provides various utility functions for Steam-enabled applications. This function takes two parameters: SteamAPI WriteMiniDump
SteamAPI_WriteMiniDump is a function within the Steamworks API that allows your game to generate a ( .dmp ) when a crash occurs. This error occurs when the Steam API isn't properly linked
This paper outlines the function, implementation, and utility of SteamAPI_WriteMiniDump within the Steamworks SDK for crash reporting and debugging. However, there is a deeper issue: the underlying
The Steam Deck runs Linux and uses Proton (a Wine‑based compatibility layer). Because SteamAPI_WriteMiniDump is Windows‑only, it simply does nothing on Steam Deck. However, there is a deeper issue: the underlying Windows API MiniDumpWriteDump (which Unreal Engine uses internally) can crash or hang on Proton, preventing any crash report from being generated at all. This is a known problem and remains unresolved as of Proton 9.0. If you support Steam Deck, you should implement a cross‑platform crash handler (e.g., Crashpad) that works on Linux natively.
Visual Studio will attempt to map the dump to your source code.
