Cubase pro 12 crash with Komplete NI 14

I use cubase pro 12 with Komplete 12, since I upgraded to Komplete 14 Ultimate, I can no more open my projects in cubase.
Cubase crashes and shuts down.
To date, I have recordings that are impossible to finalize. Do you have a solution to help me out of this situation?

Welcome to the forum!

Can you tell us what (exact) version of Cubase you’ve installed, and whether it’s Mac or Windows?’
I’m on Windows and have done the same upgrade without issue, Cubase 12.0.70.
What Komplete instruments and/or effects are in use in the projects that are crashing?

Thanks for your message and forum :hugs:
I’m using cubase pro 12.0.70 with a Mac, latest OS X. The project that crashes uses several tracks with kontakt (strummed guit - action strings -….) and effects plugins (raum -replika …) from the komplete ultimate 14 suite.


Make sure all the plug-ins are up to date, please.

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


All plug-ins are updated.
Please find attached log file.
