If you’re on Windows, you can check the Event Viewer’s Windows Logs/Application tab. It won’t give as much information as a DMP file would, but it does provide some information:
In that same vicinity, there will generally be additional entries with related information, and some of those reference DMP files. In practice, though, when I’ve looked in the locations referenced, most of the time there are no DMP files (I’m wondering if maybe Windows sends them to Microsoft then deletes them), only WER (Windows Error Reporting, I think) files (which I haven’t really found useful).
That said, though, there have been a small number of occasions, including this one, where the crash also rebooted my system, and pointed to a DMP file in C:\Windows\Minidump that was still there:
I this case, the DMP file seemed to point to a program related to my MOTU interface. (That particular problem has occurred a couple of times in the coule of months I’ve been using my new Windows 11 PC. But none of the other Cubase crashes that did not produce DMP files in CrashDumps left the DMP files Event Viewer referenced in their locations.)
Since Cubase 11, the application includes a Usage Logging feature, which is primarily intended for gathering detailed information to send to Steinberg Technical Support if you encounter problems. This logging is disabled by default.
Go to the Preferences menu
Look for the Usage Logging preference setting.
Enable the option to start recording a log of your actions within the application.
Note: The log files are not sent automatically to Steinberg. You must manually locate and send them to support when requested.
