Cubase 10.5.2 Project Freeze

Hey there,

I hope someone might be able to point me to the root of this problem.

When I jump to different bars inside a project and hit play Cubase freezes. Usually that problem only starts appearing after let’s say 10 mins of working inside the project.

I have already updated all my SSD firmwares and also made sure to deactivate some Plugins I thought causing this like Sonarworks Reference and Exponential Audio R4, which are the only things that “changed” during the last days.

It seems that it’s a disk overload that’s happening, which is weird, because the project as well as all the samples I trigger are on fast SSD drives, which are in a good condition.

I am on the latest Cubase 10.5 Version 10.5.20 Build 179 and Windows 10 Version 10.0.18363 Build 18363

Asio Performance is fine, there is plenty of headroom in both CPU and RAM.

Thanks a lot for your support!


Does Cubase freeze forever, or for some time, only? Could you create a DMP file, please?

Way 1) Could you open Task Manager, right-click to Cubase and generate a DMP file, please?

Or Way 2)
Please use Microsoft ProcDump utility to generate a DMP file.

  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 10:
    procdump64 -e -h -t Cubase10

Nuendo 10:
procdump64 -e -h -t Nuendo10

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.

Share the DMP file via Dropbox or similar service, please.
