Option+Shift+C does nothing in step input mode (macOS/Spanish keyboard)

The input pitch up key command works for every note except C.

I’ve tried multiple external USB keyboards and a bluetooth Magic Keyboard with different keyboard language layouts in both Dorico and macOS System Preferences to no avail. I’ve also made sure there are no conflicting global keyboard shortcuts in my system.

Is this more or less the same Qt framework bug of yore I’ve seen referenced in some 2017-2021 posts, or something new?

Dorico SE version / macOS 12.6.8 (Intel)

I think this C problem already appeared in the forum.

I’m having the same issue. Is there a solution yet?

No, not yet.
