Crash on exit with new Win 11 install, projects worked fine on old install

I just set up a new install of Win 11 with a new CPU but same mobo, sound card, video card, etc. and projects that previously worked fine now lock up Cubase 12.0.7 when I try to close the program. There are no error messages and there are no issues while working on the projects.

Does anyone know how to fix this issue?

Thanks in advance


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 13:
    procdump64 -e -h -t Cubase13

Nuendo 13:
procdump64 -e -h -t Nuendo13

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.

OK I just sent a link to an example DMP file via message to you.


Hi @rgames,

The crash is in the Windows library:

Please, search by Google, for how to fix it on your system.

Hi Martin - I replaced that file with the one from my laptop (where the projects close without crashing) and it didn’t help.

One thing I did figure out is if I keep clicking the red X in the top right of the window while closing the project, it doesn’t hang. But if I close the project window, wait a moment, then close the main Cubase window it always hangs.

I’m going to see if I can track it down to a particular plugin.

Any other way to debug this problem?
