Tools button isn't clickable for some users (Chrome)

The reporting user has enough reputation to use one of the tools (Change Category), but clicking on the button doesn't do anything. The question reports:

Chrome for Windows (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.102 Safari/537.36)

And a comment adds Chrome on Android.

(I can't reproduce in Chrome on a Mac.)

The console shows an Uncaught TypeError: https://i.stack.imgur.com/BOuM2.png

Transferring: the error shown in the console is what's causing this, which is part of Co-Design.
