Cubase 10 randomly crashing

Hi there, the program is randomly crashing. Sometimes it will run for a few hours quite happily, other times like tonight it has been crashing continually within 5 minutes. I can’t tie it to any one thing, crash dump is below. This is dated yesterday for some reason, it has crashed several times today but there are no dump files…

Hi and welcome,

Could you try in Cubase Safe Start Mode, please?

Here’s is another dump file from a random crash on a different system. I notice that Arpache5 and the Pool windows were open when it crashed, even though I did not open them at any time during that session…


My bad re: Arpache5 and Pool: they were opening as part of the project.

I think my case shows that it is not a Cubase Preferences problem every time there is a crash, rather Cubase has some bugs. I hoe you can make use of the crash dumps. Cubase popup said to try saving the project under a different name, that saved project will not open, says it is corrupt.

Hi Martin

I also yesterday reinstalled Cubase on a clean Windows installation, and the same thing is happening. Unfortunately there are no more crash dumps after the one I already posted above - these are no longer appearing in the Crash Dumps folder…

edit: I have started in safe mode as you suggested, after 5 minutes the program has crashed again.

So looking on another thread, there is a section in Control Panel which you can get to by searching '‘Problem Reports’ and then ‘‘view all problems’’.

This has given me the 5 reports in the attached file…

I should point out as well that the first crash was in ‘‘safe mode’’, all of the others were in normal mode… however this is a brand new installation, no prefs had been set.

The fault module name in each one is listed as ucrtbase.dll (28.7 KB)


Maybe read this article about the ucrtbase.dll crashes.


I’m in the same boat. Since I installed update 10.0.15 Cubase 10 has suffered from random crashes. No .dmp file, but an error in windows application log with Faulting module name: ucrtbase.dll
I have tried all the things mentioned in this forum, but the problem persists. I read the article about the ucrtbase.dll crashes as Martin Jirsak suggested and configured windows to create user-mode dumps. So now i’m waiting for Cubase to crash again. I also opened a support case at Steinberg yesterday.
I will let you know if/when I find a solution.


I have read the above thread, which looks like it relates to a printer issue.

I realised that when I said ‘‘clean’’ Windows installation, it was just a reset of Windows 10.

I have now done the following.

  1. Reinstalled Win10 from scratch using Windows Media Creator tool.

  2. Installed nothing except for Google Chrome, my Focusrite 2i4 driver, and Cubase. No other 3rd party programs or plug ins of any kind.

  3. Run Cubase. Create new project.

  4. Come back a random time later to find it is no longer running.

  5. No crash report in Steinberg / Documents, but in Event Viewer it is listed as Error Type 1000 (application error).

  6. It is also listed in Control Panel\System and Security\Security and Maintenance\Problem Details

I’m at a loss.


Please attach the source *.dmp file (located in Documents/Steinberg/Crash Dumps folder).

But here, actually, I can see the bex64 error. This is Microsoft error. Please search Google for bex64 error.
