Using --disable-store-sdk causes a fatal error
Done • Priority: High • Fix: None • Game: 1.0.0-modding-beta-3 • Resolution: Duplicate

Using the --disable-store-sdk command line argument causes a fatal error in shapez 2. The issue occurs when creating a shortcut to the game executable, adding --disable-store-sdk to the target path, and launching the game through that shortcut. The fatal error is triggered immediately upon startup. The expected behavior is that the game should launch normally when using this command line argument without triggering any fatal errors.

NullReferenceException: Object reference not set to an instance of an object - Steamworks.SteamApps.IsSubscribedToApp
To Do • Priority: Low • Fix: None • Game: 0.0.9-rc6

NullReferenceException occurs when the game tries to check if the player owns the Supporter Edition via the Steam API, but the Steamworks API returns a null reference. This happens when the Steam client is not running, not properly initialized, or the user is in offline mode. The game cannot verify DLC ownership and may crash or fail to unlock Supporter Edition content. The error originates from the IsSubscribedToApp call in the Steam integration code. Impact: players cannot access purchased ...

--disable-store-sdk launch argument prevents game to launch when preload intro has not yet been seen
QA • Priority: Highest • Fix: 1.0.3 release (Hotfix 1) • Game: 1.0.1-rc1

When launching shapez 2 with the --disable-store-sdk launch argument on a fresh install where the preload intro has never been seen, the game fails to launch. The failure is caused by a graphics initialization check for Steam Deck that incorrectly assumes the Steam SDK is initialized. This affects users who have not completed the preload intro prior to the settings refactor introduced in recent betas. Clearing the settings folder in the game data directory replicates the issue. The game shoul...

Initialization failure due to (incorrect) unknown windows version.
Done • Priority: Medium • Fix: OLD Early Access • Game: 6.2.9200 • Resolution: Won't Fix

Multiple players are experiencing an initialization failure in shapez 2 where the game incorrectly detects their operating system as an unsupported version. After the initial credits and loading screen at startup, an error message appears stating the operating system is not supported and requires Windows 10 or newer, even though affected players are running Windows 10 or Windows 11. The game displays "Unknown Windows ()64bit" in the bottom left corner. This prevents players from accessing the...

A temporary fix is to add ´--disable-store-sdk´ to the launch options
