InDesign 18.1 on Mac OS 13.2.1 Ventura - Data merge for email QR codes specifically doesn't work, and your documentation is frankly non-existent. Using the MATMSG format doesn't produce a working QR with Data Merge, but using HTML format mailto in Plain Text does. I'm sure I'll run into the wrong version VCARD problem soon, too.

This is consistent using the MATMSG format in a .csv with data Merge. Using the manual entry isn't a workable option due to the quantity of codes being generated.
