Perhaps its a right management thing, only.

Check your system settings with Security and Privacy and allow InDesign full disk access.

What did you try?

My guess is that InDesign has some issues with its cache and/or preferences.

Plus perhaps InDesign needs more rights with accessing all files and folders in the file system.

Check the security settings of your user of macOS.

Hm. Also add a new user to your machine and try again after logging in to your machine to the new user and after you did the following:

Uninstall InDesign. Log out from the Creative Cloud Desktop app. Restart your machine.

Log in again to the Creative Cloud Desktop app and install InDesign again.

Thanks,

Is that a new symptom? did it start to happen after an update or upgrade?
