Version:
Adobe InDesign 21.1 (macOS)

Steps to reproduce:
1. Open any document in InDesign 21.1
2. Select a text frame or an image frame
3. Press Option + Command + C (Fit Frame to Content)

Expected result:
The selected frame resizes to fit its content.

Actual result:
Nothing happens. The shortcut does not execute.
The command is still listed in Keyboard Shortcuts and cannot be removed.
Double-clicking the bottom-center resize handle still works.

Notes:
This is a regression from previous InDesign versions.
The issue affects both text frames and image frames.
