SteamAPI_Init() failed, after recent steam update on Arch Linux on m_pSteamHTTP == IntPtr.Zero

[tg-roshiroku]

internal static bool Init() {
    HSteamUser hSteamUser = SteamAPI.GetHSteamUser();
    HSteamPipe hSteamPipe = SteamAPI.GetHSteamPipe();
    ...

// Here it fails
    m_pSteamHTTP = SteamClient.GetISteamHTTP(hSteamUser, hSteamPipe, Constants.STEAMHTTP_INTERFACE_VERSION);
    if (m_pSteamHTTP == IntPtr.Zero) { return false; }
    
    ...
    return true;
}

Tried on windows, it works fine with the same account. When running game in Unity Editor, the Steam does inform me that I'm playing the game.

Steam log:

Game Recording - would start recording game XYZ, but recording for this game is disabled
Adding process 80272 for gameID XYZ

I'm looking for a potential fix / information what is wrong.

Appears to be related to changes in the latest Steam Client Beta. Opting out of Steam Client Beta Participation solves the issue but I fear that breaking changes are coming in the next stable release of the Steam client.

Have also made a thread in the Steam Beta group discussion https://steamcommunity.com/groups/SteamClientBeta/discussions/0/612032374411181176/

Had the same issue yesterday (on windows), changing from non-beta client fixed it

Apparently this issue was solved by Valve in the latest Steam Client Beta patch: https://store.steampowered.com/news/group/4397053/view/605276452911318951?l=english
