Crash Immediately On Launch (Mac)

Confirming the same crash on M4 Pro / macOS 15 / Rosetta 2.

System:

• Mac16,8 (M4 Pro)
• macOS 15 (Sequoia)
• ONI running under Rosetta 2 (x86_64 translated)
• Steam version, build ID 22804477, Unity 6000.3.5f2

Crash signature:
The triggered thread is always AssetGarbageCollectorHelper. It crashes with EXC_CRASH / SIGSEGV immediately after waking from a dispatch_semaphore_wait, before the game shows anything on screen. There are 11 AssetGarbageCollectorHelper threads active at the time of the crash.

Triggered thread stack:

[Rosetta JIT cache]            ← SIGSEGV here, accessing freed memory
semaphore_wait_trap
_dispatch_sema4_wait
_dispatch_semaphore_wait_slow
[UnityPlayer.dylib ×4]
_pthread_start
thread_start

Main thread at time of crash:

__NSFireTimer
__CFRUNLOOP_IS_CALLING_OUT_TO_A_TIMER_CALLBACK_FUNCTION__
[UnityPlayer.dylib — unity_operator_delete_dealloc]
_DPSNextEvent
-[NSApplication run]
PlayerMain
start

 

Ruled out as causal issues:

• Verifying game files — no change
• Disabling Steam overlay — no change
• macOS update — no change
• The crash is unrelated to the SDL joystick crash (separate issue, separately fixed)

Happy to attach a full .ips crash report or Player.log if helpful.

When was the last time you were able to play the game? If you switch to the public_previous_update branch on Steam does it work for you? (right click the game in Steam -> Properties -> Game Versions & Betas)

@EricKlei I've never played ONI on a Mac before; I used to play on Windows, and just recently tried to switch since I got a new Mac.

Using public_previous_update on Steam doesn't fix the crashing, unfortunately.

That rules out the recent Unity upgrade in the current version of the game, thanks. The crash is from the Unity Engine and not the game code so our options are limited. Is there a newer version of Rosetta you can update to?

@EricKlei The issue appears to be with Razer Synapse! Disabling the Razer Virtual HID Driver Extension allowed the game to launch fine. (I found the solution here: https://us.forums.blizzard.com/en/hearthstone/t/cannot-open-hearthstone-error-reopen-then-nothing/157182/9). Thank you for your help!
