Cubase Pro15 freezing bugs - should I revert back to V14?

Cubase

Having a bit of a problem with CB Pro 15 freezing on my PC. The project only has MIDI tracks with 1 VST (Halion 7) not heavily loaded. I do have access to 14, maybe I was too anxious to upgrade?

Hi,

Do you have any Cubase 15 *.dmp file?
Win: %userprofile%/Documents/Steinberg/Crash Dumps

If yes, attach them here, please.

If not, generate a DMP file and share it via Dropbox or a similar service, please.

Use the Microsoft ProcDump utility to generate a DMP file, please.

  1. Please download ProcDump64 from Microsoft (~650kB) and extract the archive to a local folder on your hard disk.

  2. Run Command Prompt (cmd) as administrator (right click and select “run as administrator”)

  3. Navigate (in the Command Prompt) to the folder with the extracted procdump file.
    For example:
    cd C:\ Users \ \ Downloads \ Procdump
    Note: the dmp file will be written into that folder.

  4. Launch Cubase/Nuendo. You can work as usual. At any time, change to the command prompt and start procdump, to monitor Cubase/Nuendo for unexpected behaviour (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase:
    procdump64 -e -h -t Cubase

Nuendo:
procdump64 -e -h -t Nuendo

The -h option will write a dmp file in case of an application hang. This might kick in too early sometimes, in case some action takes a little longer. Feel free to skip the “-h” option, if you are only up for fetching crashes.
The option -e will catch exceptions and the option -t terminations of the application.

  1. Prodump is now monitoring the Cubase/Nuendo process and will write a crash log, in case Cubase/Nuendo crashes or hangs. Perform the action that causes Cubase/Nuendo to crash and send us the generated crash dmp.

ZIP and share the DMP file via Dropbox or a similar service, please.

Yes, I have 3 previous freeze crash dumps.
But I assumed since after recovery from each crash, I got a message box saying the crash dump was automatically sent in.
Am I mistaken?

​Cubase 15.0.6 64bit 2026.1.3 22.18.27.648-freezedump.dmp​
​Cubase 15.0.6 64bit2026.1.6 23.06.15.079.dmp​
​Cubase 15.0.6 64bit 2026.1.3 13.53.00.709-freezedump.dmp​

One of the freezedumps crashes WinDbg so is undecipherable.

The other freezedump shows a crash in msvcp140.dll which is associated with the C++ Redistributable for Visual Studio.

The third dump shows an unidentified error within Cubase.

It is possible that you have an older or corrupt C++ Redistributable library installed.

I would suggest reinstalling the latest version (it is harmless to do so).

I would also suggest opening an admin level command prompt and running

sfc /scannow

and letting it scan your system. If it finds damaged windows files it will attempt to replace them. Once it’s finished it will tell you if any damaged files were found.

Note that the sfc command will not correct an out of date C++ library. That needs to be done via a reinstall
