Game crashes on launch on macOS - unable to reach main menu
To Do • Priority: Highest • Fix: None • Game: 1.0.3-rc3

shapez 2 crashes immediately on launch on macOS, preventing the player from reaching the main menu. The issue appeared suddenly after the game had previously been working, with no known triggering action from the user. The expected behavior is that the game should launch successfully and display the main menu without crashing.

Crash on startup
Done • Priority: Medium • Fix: Version 0.0.9 • Game: 24.2.2 • Resolution: Won't Fix

shapez 2 crashes on startup with a SIGSEGV error when running natively on Linux, likely triggered by recent OS package updates (such as mesa, mutter, vulkan-loader, or xwayland). The game was previously working but newer package versions broke compatibility. Running under Proton appears to work as a workaround, though sound issues were also reported. The crash occurs in native code before the menu is displayed. This is not something the development team can fix on their end, so using Proton i...

Crash during startup process
Done • Priority: Medium • Fix: Future • Resolution: Won't Fix

The game / shapez 2 crashes during the startup process on Linux using Proton support. The crash occurs right after clicking allow anonymous reporting on first launch. On the second launch attempt after clicking the same option, the game successfully reaches the start menu. The log shows multiple errors including a 32-bit library being incorrectly loaded into a 64-bit process and Chromium embedded browser component issues. The crash prevents the player from accessing the game on first startup,...

[Linux] The title will end straight after starting a few times before starting properly
To Do • Priority: Medium • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu, Arch), shapez 2 crashes immediately after launching multiple times before eventually starting properly. The issue is triggered by a fatal runtime error in the Mono runtime or one of its native libraries, with native fault reporting also failing, which leaves some diagnostic information unavailable. The expected behavior is that shapez 2 should start properly on the first launch attempt.

[Linux] Title always exits shortly after starting it
To Do • Priority: High • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu and Arch), shapez 2 crashes shortly after launching, though not 100% reproducibly. The crash appears related to native resolution, as it can be worked around by using a non-native resolution or by manually creating a display.json file with a specific resolution and windowed mode. The log shows a fatal runtime error in the Mono runtime or native libraries. Expected behavior is that shapez 2 starts successfully every time without requiring manual configuration changes.

CRASH after Dev Warning - StackOverflowException: The requested operation caused a stack overflow.
Done • Priority: Highest • Fix: Version 0.0.9 • Resolution: Done

shapez 2 crashes with a StackOverflowException after confirming the DEV Warning on game launch, preventing the player from reaching the main menu. The crash occurs when loading a Savegame and accepting the dev warning dialog. The stack overflow is caused by infinite recursion in the ISpacePathInput connection system, specifically related to Space Belts or Space Pipes pathfinding. The error log mentions a missing serialized upgrade for Pump Booster. The issue has been marked as already fixed a...

crashes right after loading achievements screen, game ran just fine during EA, crashed like this with all 3 launch options. Fresh install

Weird, verifying files through steam managed to get it to launch. Seems like a unique unreported crash condition, worth examining still?

Hi @deft ledge

This sounds like it was related to an error in the download or install, but not something we can action on (and may of been something unrelated to the code). I'm going to close this ticket, but if it occurs again please follow up with additional information.

Thank you,
Josh
