Build a Pi 3.2.0 and later does not support

You should consider upgrading to RaspiOS 11
(Bullseye). By clicking ok you will be moved
to the last version of Build a Pi (3.1.4) that 
supports Pi OS Buster. Please note there are 
no plans to update Build a Pi for Buster going 
forward.  In other words, you are on your own
