I just noticed that I have this issue on existing projects.
When trying to change the sample rate from 44.1/24 to 48/24 Cubase crashes.
I can barely see the dialogue about conversion of the files sample rate, (convert button looks “pressed” already), and then Cubase crashes to desktop.
No issue on changing new projects from one sample rate to the other, everything is happening smoothly.
Most of my templates are created with older versions of Cubase, from 8 up to 9.5
Me too. Converting from 96 to 48.
I have made all files in pool musical mode and same tempo but after last dialogue box it starts processing files then just closes Cubase.
I’m on C12.0.0 (can’t update to 12.0.4 as had too many issues with SonarWorks SoundIDref. & audio connections lost etc.)
