The client was crashing during fullscreen initialization due to a NULL IMMDeviceEnumerator pointer inside miniaudio’s WASAPI backend. Crash location: ma_IMMDeviceEnumerator_GetDefaultAudioEndpoint (inlined in ma_device_init_internal__wasapi) Disassembly showed a null vtable dereference: call qword ptr [rax+20h] On some systems, WASAPI fails to create or retrieve the default audio endpoint (especially in VMs, RDP sessions, missing/disabled audio devices, or timing issues during fullscreen initialization). This results in a NULL COM pointer being used, causing a 0xC0000005 access violation before the game window fully appears. Solution: WASAPI backend has been disabled and the client now falls back to the more stable DirectSound/WinMM audio backends. Applied definitions: #define MA_NO_WASAPI #define MA_ENABLE_DSOUND #define MA_ENABLE_WINMM Results: ✔ Fullscreen crash completely resolved ✔ Audio still works through DirectSound ✔ Improved stability across fullscreen/windowed modes ✔ No functional drawbacks observed
