I’m reporting a crash in Cubase Pro 15.0.30 (64-bit) on Windows 11. I’ve analyzed the
crash dumps myself and believe I can point you at a specific fault, including evidence
that the same defect existed in Cubase 14.

THE CRASH
Dump file: Cubase 15.0.30 64bit2026.7.11 16.58.11.830.dmp (can share privately)
Date/time: 2026-07-11 16:58:12
Exception code: 0xC0000005 (ACCESS_VIOLATION)
Operation: READ from address 0x0000000000000008
Faulting module: Cubase15.exe (not a third-party plugin)
Faulting offset: Cubase15.exe+0x4AB899C
Faulting thread: 9020
A read of address 0x8 is the classic signature of dereferencing a NULL pointer and
accessing a member at offset +8. It looks like a missing null check on a pointer that
can legitimately be null.
THIS IS NOT NEW — IT ALSO HAPPENED IN CUBASE 14
2025-01-02 Cubase14.exe v14.0.10.144 +0x4AB6F7C READ from 0x8
2026-07-11 Cubase15.exe v15.0.30.287 +0x4AB899C READ from 0x8
Two different major versions, both faulting on a read of address 0x8, at offsets only
about 6 KB apart within the executable. To me this strongly suggests the same defective
function, carried over from Cubase 14 into Cubase 15. I can’t confirm that without your
private symbols — the offsets are what I can see from the outside — but it should be
immediate to verify on your side by loading the attached dumps against your PDBs.
I’m happy to provide the full crash history (I have ~94 dumps going back to 2024), the
project file, or to run a debug build if that would help.
