Cubase 12 crashes and freezes


Having issues with my Cubase setup.

Windows 11
Cubase 12
Steinberg UR22MK2
Roland A-49 Keys

So this is not a crash, but a freeze that you dump with procdump? What did you do to make Cubase freeze?
I see this in the dump:

Do you by any chance have a MIDI track in the project that has the “Microsoft GS Wavetable Synth” as output? Can you remove those and try whether that helps?


I just open up a project and it freezes. Does not matter witch project. All the same. I can try to deactivate the MIDI.

And yes, it freezes and i used the dump function.

Hi again. This did not solve the issue. I also are getting issues regarding loading the projects as well, it takes a very long time and it seems to land on Kontakt instances everytime.

Have you tried opening the project in safe mode with third party plugins disabled? If that works, it’s most likely some plugin (I’ve actually had older versions of kontakt freeze on me, but usually only when searching for missing samples)

It may be. Is there any way to do a analyze when starting up? Needle in a haystack if not.


A update. Found out that the SSD drive I had Kontakt installed on was faulty and a slow SSD compared to the M2 disks I have.

So when I benchmarked the SSD it got very low score. So now I have installed another M2 disk to see if it loads faster.

Cubase always halts on Kontakt when loading a big project.

Runs like a charm now with the new disk.
