After about a minute of that (more or less), The display goes mostly blank, with a 'low-voltage' lightning bolt in the top right of the display (this lightning bolt comes and goes over time, mostly gone). This effect happens with ea h of two 6A power supplies that I have tried.

The non-comment, non-blank lines from /boot/config.txt are:

What might I be doing wrong?

If the course code on your CrowPi desktop uses RPI.GPIO library, but you are using a Raspberry Pi 5, you can install the course for Raspberry Pi 5 in the following steps.
1.Open the terminal, and go to a directory where you will place the course. I will place the course on the desktop, so I type cd Desktop and press "Enter" to run this command.

2.Then run the following command to clone the lessons code to CrowPi desktop.
git clone https://github.com/Elecrow-RD/CrowPi_RPI5.git

3.After the lessons code is downloaded, you can enter the course code directory through cd Desktop/CrowPi_RPI5/Examples, and then run the corresponding course program in this directory.
For example, when I need to run the buzzer program, I will run
cd Desktop/CrowPi_RPI5/Examples
then run
sudo python buzzer.py
