Memory problem generating QR code

Problem/Motivation

When I install commerce ticketing in a clean version of Drupal 9.5, everything works fine except the QR code display option. If I use "Ticket QR Code", I can't display the ticket because everything runs out of memory.

Here are some of the errors in the Apache2 error.log file:
