Cubase 15 Pro Crash Dumps

I wonder if any of you guys can help with a problem. For two months now I have been experiencing Cubase crashes. It is now happening up to 10 times a day if I have a long day.

I am a long time Cubase user (since Cubase VST in 1996) and have sorted many problems out over the last 30 years but this one is defeating me.

I have an i9 top spec Scan PC with 32Gb RAM purchased and set up in Jan 25 so there is no problem with hardware.

Here are some of the things that I have done in order to stop these crashes:

Run fc /scannow and dism /online /cleanup-image /restorehealth

Reinstalled Cubase 15 Pro

Reinstalled and updated drivers for:

My RME FIreface UFX II;

My NVIDIA GeForce GT 1030Graphic Card;

My Launchkey 61 MIDI Keyboard;

All intel components;

I have disconnected my RME interface

I have removed all third party VST plugins

I have removed all Steinberg plugins

I have open a fresh blank Cubase project and not touched the keyboard or mouse for an entire day!

Cubase still crashes.

I have raised a ticket with Steinberg weeks ago with no response.

I have tried analyzing the crashdumps in WinDBg but I don’t really know how to interpret these.

Do any of you fine fellows have any new ideas or know how to interpret Crash Dumps?

Did you mean to post the crash dumps here so others could look at them? There was nothing attached to your post.

Hi Pete, here is the last one from earlier today. Thanks

Cubase 15.0.10 64bit2026.3.5 10.03.33.339.dmp (1.5 MB)

I can see why you had challenges looking to figure out the cause. The dump doesn’t really point to anything there that’s useful, at least not looking at it without access to Cubase debug symbols.

Have you talked with Steinberg support?

Yep, the crash dump not useful…

But just to get a clear picture: Those crashes happened since you bought and installed your new computer? From the beginning? Or did it work at first and the suddenly they started?

Have you tried moving Cubases’ preferences folder and start with newly generated preferences files (go to ā€œ%APPDATA%\Steinbergā€ and move the ā€œCubase 15_64ā€ folder e.g. to your desktop, then start Cubase and see if the crashes still occur.

Just out of curiosity I’d like to see more than one dump to see if the failure occurs at the same place or if it’s random.

Can you post two or three more?

Thanks.

Hi, no my new PC ran from Jan 25 up until just after Christmas. This problem started out of the blue. I have had no change in hardware. I have probably added some plugins but it is hard to remember which ones. I will try your suggestion of moving the preference files later today. Thanks very much.

Thanks. I’m away today but I’ll have a look at these tonight.

Hey, that’s really kind of you. Thanks

The crash dumps all have the exact same error, but as Pete already wrote, it is pretty much impossible to say what went wrong, this is something only Steinberg can tell.

Four of the dumps are invalid pointer reads and one is an invalid pointer write. All of them are access violations which means something in Cubase was trying to read or write to memory that it shouldn’t be.
There’s virtually nothing in the call stack so it’s impossible to determine a chain of events leading up to the crash.

Given that the vast majority of us are not experiencing these crashes I have to suspect something in your machine is going south.
Have you tried running memtest?

Hi There,

I have run memtest with no errors. Still waiting for a Steinberg reply.

What about the preferences thing, did that change anything?

So, what @fese said about preferences. It’s always worth renaming the preferences folder and restarting Cubase to see if it clears the problem. Also, if you have a previous version of Cubase installed, rename its preferences folder as well or Cubase will try to pick it up on restart.

Is this fresh project from a template or is it literally created from empty?

Hi @David_Clark , this is Chriss from Steinberg’s audio engine team.

Thanks for the crash dumps - we have analyzed them but can only conclude that there’s memory corruption leading to the crash. But why and which origin is not revealed in the crash dumps. So we’ll definitively need a system trace to understand the genesis of your crashes. I’ve just sent a PM with the instructions.

All the best

Chriss

Dear All, thanks for your help with this. I tried everything detailed above but nothing worked. I ran multiple different memory tests. All passed. I moved preferences folder. In the end I went back to Scan Computers just in case they could think of something. WIth their advice, I now seem to have resolved the problem. It would appear that the combination of three things may have caused this problem:

  1. Bios out of date - I carried out a bios update. This is not something that I have done in nearly 40 years of using PCs.
  2. Making sure that Microsoft Edge is not running when I use Cubase. This is annoying and will have to migrate to another browser now.
  3. Running ā€˜View Reliability History’ is a new tool to me. This has highlighted files from other programmes that may have caused issues (e.g. SDXHelper.exe, MsMpEng.exe). I have renamed some of these files to stop them from running with currently no noticeable effect.

The combination of these changes has resulted in Cubase now running for a 24 hour period without a crash for the first time in months. I will post any further updates if anything changes.

Cheers

Dave

Was there any explanation given for this? Chrome and Edge share the same engine, as do many other browsers and web apps.

I’d be inclined to see if that really is the issue, or if it’s more someone pushing an agenda.
