Hi, same problem here.

Fixed it this way:

It is possible to set custom shortcuts via Tools > Customize > Interface > Shortcuts.

For some reason AutoCAD doesn't accept setting for example "Undo" to "CMD+Z" and keeps "CMD+W".

However changing it to some other value (i.e. "CMD+SHFT+A") creates a custom shortcut file under "/Users/<USERNAME>/Library/Application Support/Autodesk/AutoCAD LT 2024 Standalone/R24.3/roaming/CUI/Accelerator.cui"

You can edit this file with a text editor (textEdit on mac).
