CUBASE 12 Pro - Start and freeze

I bought Cubase 12 Pro (upgrade from C11) this morning and i already installed it.

C12 (v12.0.0) starts normally, it open the starting page with old c11 projects list, “create new” button, etc.

If i open an old C11 project OR if i start new project (is the same), C12 gui opens normally but it seems feezed and i can’t do nothing. No play, no interaction, it seems freezed.
The only thing i can do is kill the task on win task manager (that is regular, no “not responding”)

I already rebooted, deleted cubase pref file, config file, disabled third-part plugins, changed audio devices, nothing.
I don t have third-party plugin ad all, i use Cubase for audio editing.

Do you have some suggestions to solve that?

Ps: Cubase 11 already starts and run fine.

All you can do is use 11 until they fix it,
you’re not the only one having these issues

It’s a dual display problem. If i use only 1 monitor, it works.

Generate a DMP file and share it via Dropbox or similar service, please.

Use 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 harddisk.

  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 behavior (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase 12:
    procdump64 -e -h -t Cubase12

Nuendo 11:
procdump64 -e -h -t Nuendo11

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 exeptions 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 similar service, please.
