Hi and welcome to the forum,

Make sure you have the latest Yamaha/Steinberg Tools installed, please. Also make sure Cubase is up to date.

If it’s still crashing, attach the *.crash file, please.
Mac: macOS Console utility > Crash Reports (or ~user/Library/Logs/Diagnostic Reports).

I don’t see any relation to the driver in the crash. There are Cubase processes, then Steinberg Hub, then one more Cubase and then it crashes.

As a workaround (for now), you could try to disable Hub in the Preferences > General.

You could also try to delete Cubase and install it again.

Could you try in the Cubase Safe Start Mode [Disable preferences], please?

Reported to Steinberg. Thank you.

yes I had tried the various options of safe mode. that did not work either. If the app does not crash which it did only once it then freezes, the color wheel keeps turning. The dock of the mac even freezes also. I have de-installed everything and will re-install again. I beleive it is not a version issue as all is downloaded straight from Steinberg. Thanks again, I shall update. Kind regards


Do you have the latest Yamaha/Steinberg Tools for UR-C installed, please?

eLCC shouldn’t play any role in this.

plugged the UR22C
started Cubase
Cubase is freezing but not crashing the colored wheels keeps turning
I have tried every options of disabeling plugins/prefs etc
I unplug the UR22C
restart Cubase
I select a different Asio such as integrate audio the app works
I replug UR22C the colored wheel turns the app freezes
I tried to check if the problem is similar with Garage Band it works
Any suggestions ?

Kind regards

Hi Denis,

Start Cubase with built-in Audio. In the Preferences > General disable Steinberg Hub. Quit Cubase. Plug UR22C. Start Cubase and select the UR driver. Does it work?

good evening Martin
no it doesn’t still the same
howcome when the app starts even without the UR22C plugged I get the screen "the app was terminated unexpectedly (attached) ?
would it be due to a clash between the various audio shown in audi configuration (attached in the next message)

Kind regards


You get the message during the next start after the last Cubase crash. So if you get the message always (even if you start Cubase 3 times in line workout UR and you always get this message), this means, there is something out of UR.

Dear Martin,
can you please clarify “there is something out of UR” I did not quite understand.
wether UR22C is plugged or not plugged I do get the safe mode error message.
Kiind regards


Your title and the description say, you get the crash only if UR device is plugged in.

Now it seems it doesn’t matter and Cubase crashes always.
