I just checked, and the script above still working (PS. no need to restart anything), however, two things need to be done.

Close TeamViewer (make sure it is not working in the background as well).
Close Terminal as well.

macOS 15.3.2

1. Settings > Privacy & Security > Full Disk Access

Turn ON for Terminal

2. (optional) Settings > Privacy & Security > Deceloper Tools

Turn ON for Terminal

Then in Terminal

sudo python3 TeamViewer-15-id-changer-for-mac.py

Type your password and when requested, hit Enter and wait until finishes.

TeamViewer 15.63.4

You will need to re-do this after each TeamViewer update.
