OSX 14.8.2
No obvious cause. Had had no issues previously, but last few days been happening within minutes of project being open. Complete crash - one second it’s there, next second entirely gone. Have been deactivating various plugins bit by bit to try find the culprit, but no joy so far.
Is anyone able to interpret the diagnostic reports please? As it has rendered the program unusable and really bloody annoying.
Thanks!

Hi and welcome to the forum,
Any change happened in last few days? Any update (system, Cubase, plug-in)?
The actual fault: heap corruption detected by macOS’s allocator (nanov2_guard_corruption_detected → malloc_zone_error → abort). It triggered during an FFT setup allocation (vDSP_create_fftsetup) called from Cubase code. So Cubase code corrupted the heap and the next malloc (Apple’s vDSP framework requesting memory) tripped the guard. The crash surfaces in libvDSP/libsystem_malloc, but those are just where the pre-existing corruption was caught — the originator is the Cubase code in frames 11–32.
Worth noting: heap corruption crashes are non-deterministic, and the cause could still be a plug-in that scribbled over memory earlier on a different thread, with the damage only detected here.
Thanks for the response Martin. No recent OS, Cubase or plugin installs/updates. I’ll try to bounce down and remove plugins bit by bit then perhaps save a new copy? See if it makes any difference.. cheers for your help.
