I upgraded STM32Cube IDE to 1.12.0, and now when I double-click the IOC file, it just displays a text file, not the processor pin / configuration diagrams, etc. I tried closing and re-opening the project(s) and closing and re-opening CubeIDE. No change.

STM32CubeIDE v2.0.0 does not support IOC files natively.
Use standalone STM32CubeMX to view and generate code.

1.12.0 is like over 2 1/2 years old. At least upgrade to 1.19.0
Starting with STM32CubeIDE 2.0.0, you'll need to use STM32CubeMX to create the IOC.
