Hello everyone,
I am trying to use Steamworks sdk to get Steam user id.
The following is a small reproductible example:

#include <iostream> #include <steam_api.h> #include <isteamapps.h> #include <isteamfriends.h> #include <isteamuser.h> int main(int argc, char const *argv[]) { SteamErrMsg errMsg; if (SteamAPI_InitEx(&errMsg) == k_ESteamAPIInitResult_OK) { auto steamUser = SteamUser(); if (steamUser) { std::cout << "SteamUser() is valid." << std::endl; try { CSteamID steamID = steamUser->GetSteamID(); std::cout << "SteamID: " << steamID.ConvertToUint64() << std::endl; } catch (const std::exception &e) { std::cout << "Exception occurred" << std::endl; } } else { std::cout << "SteamUser() is nullptr." << std::endl; } SteamAPI_Shutdown(); } else { std::cout << "Failed to initialize Steam API." << std::endl; } return 0; }

With gdb, we can see the crash occurs in a steam function of steamclient.dll, on that line: CSteamID steamID = steamUser->GetSteamID();

warning: [S_API] SteamAPI_Init(): Loaded 'C:\Program Files (x86)\Steam\steamclient64.dll' OK. Setting breakpad minidump AppID = 3025660 SteamInternal_SetMinidumpSteamID: Caching Steam ID: 76561198137762511 [API loaded no] Initialize Steam API OK. SteamUser() is valid. Thread 1 "MainThrd" received signal SIGSEGV, Segmentation fault. 0x00007ffead18e225 in steamclient64!Steam_NotifyMissingInterface () from C:\Program Files (x86)\Steam\steamclient64.dll

I tried with different version of steam sdk.
I tried reinstall Steam client.

On Linux the code provided works perfectly.

I have also tried to have more info withing the steam consol steam api debug describe here.

This is the most verbose output I have during the execution of my example program. I didnt find anything suspicious.
