I'm trying to create an empty project for the NUCLEO-U3C5ZI-Q using STM32CubeIDE v2.1.1 under MacOS. All available updates have been applied.
I've used File/STM32 Project Create to create an STM32CubeIDE Empty Project for the NUCLEO-U3C5ZI-Q board (all settings at the defaults offered).
The project is created, along with the startup and linker files, but there is no .ioc file.
Solved! Go to Solution.

STM32CubeIDE v2.0 and later do not create IOC files or STM32 projects. The ability to interact with IOC files has been removed. Use the standalone STM32CubeMX for that.

Indeed - I was just coming back to say the same thing ;)

As @TDK said, this was an intentional change in CubeIDE v2.0.0, back in November last year (announced in September):
See: STM32CubeIDE 2.0 release - early heads-up!
And: STM32CubeIDE 2.0.0 released
New tutorial here: STM32CubeIDE 2.0.0 workflow tutorial
Explanation & discussion here: IDE Version 2.0.0 - why remove MX ?
