I have this exact problem as well. Completely new hardware, but good old Windows 7 SP1 x64 Ultimate (and all updates) installed. Cubase 9 and Cubase 9.5 fail in the same way, as described by the other posts. Which update to 9 or 9.5 doesn’t matter (interestingly, Cubase 8 and 8.5 are fine). There are no other third-party VST available to Cubase when these crashes occur.
The user-visible symptom is the crash while “Initializing: VST Mixer” is visible on the logo screen. The exception is 0xC000001D (invalid instruction) in Cubase Plug-in Set.vst3. Just like in the original post, removing this vst3 file allows Cubase to start but it will crash upon doing something that (presumably) requires functionality from that set of plug-ins.
My specs are similar to the original poster’s:
i7 7800X, ASUS Prime X299-A motherboard with 32GB, Windows 7 Ultimate SP1 64-bit, ASUS GL1030 2G graphics card (NVidia chip), M-Audio M-Track 2x2 (via USB)
Could this be the problem mentioned elsewhere that Cubase 9.5 is having with some of the recent NVidia cards?
I even did experiments of freshly installing (on a separate SSD) Windows 7 SP1 on the same new hardware, except using an older graphics card that I know works with Cubase 9.5, but I got the exact same problem.
Could it be x299-chipset or 78x0X related? That seems a common theme here. Maybe not even specific to Windows 7, as there even is a post on another forum (for Mac users apparently) of this symptom on an x299 with a i9-7900X.
I have dozens of crash dumps from various experiments trying to isolate, work-around, remove/add (under the assumption that my new build has some issues with BIOS settings, internal audio driver conflict, Microsoft’s hotfix support for NVMe SSDs, etc.), but how should I share one of those here?
It seems this is a rare problem as there are few posts with these symptoms, so I do want to add another customer to the list of those who are.
