Cubase 14 and 15 keep crashing at opening saved project. MacOS & AXR4U

Hi! My Cubase projects keep on crashing and this started when I upgraded to Cubase 14 and now 15 (in the hopes it would have been solved)

I have now narrowed my issue down to the following and absolute minimum to have Cubase 14 and 15 crash when re-opening a saved project:

  1. start Cubase
  2. create an empty project
  3. save the empty project
  4. close Cubase
  5. start Cubase
  6. open the saved empty project without issues (no crash even when I wait or press play and stop)
  7. I add an audio track and use the default “Stereo ln” settings which adds Mic1&2 of my AXR4U as inputs of this new and only track
  8. I save the project
  9. close Cubase
  10. start Cubase
  11. open that saved project that now just holds one empty audio.
  12. Cubase shows the project for half a second and
  13. crash / Cubase unexpectedly quits

Cubase 15-2025-11-19-164950.ips (160.7 KB)

These are just two of the numerous crash log files.

Please let me know if there is anything left to try, I narrowed my issue down to this thus far and hope it is not a AXR4 driver issue, because I noticed that with later AXR4U driver updates from yamaha only support Apple silicon and not x64. and I am working on an 2017 Apple iMac Pro, which is still using an intel chip for CPU ….

Thank you

NB: When I select internal audio as audio driver, all seems stable. This is the way I get into older projects to have access to them again, but of course I lose all of my audio interfaces this way and the sound no longer comes from my studio speakers but from the internal speakers in the iMac….

Hi,

I’m sorry to hear about your bad experience. Reported to Steinberg. Thank you.
