Black screen on Pi 4 and hyperpixel 4

I am getting a blank screen after an installation from scratch. When I reboot the display flashes with some content which tells me that hardware is somehow working.

To Reproduce
What install steps did you go through so far? Did you install from GitHub or use our one-line-installer?
Brand new Raspberry Pi OS installation + I followed the github install for the pi 4 https://github.com/pimoroni/hyperpixel/tree/pi4

Your HyperPixel 4

1. Is it Square or Rectangular? Rectangular
2. Touch or non Touch? non
3. Approximately when was it purchased yesterday
4. How is it connected to your Pi: pins supplied in the box

Your Raspberry Pi
I bought the Pi 4 about a month ago

1. What model of Raspberry Pi are you using (the result of cat /proc/cpuinfo | grep Revision can tell us this exactly:
   Revision : d03114
2. Which OS release are you using: lsb_release --description and uname -r
   Description: Raspbian GNU/Linux 10 (buster) and uname= 5.4.51-v7l+
3. Is this a fresh OS setup, or one you might have previously installed scripts/add-ons on? Fresh

Extra debugging information

If you’re having a problem with touch, try checking dmesg for related errors:

pi@raspberrypi:~ $ dmesg | grep Goodix
[ 5.605515] Goodix-TS 11-0014: 11-0014 supply AVDD28 not found, using dummy regulator
[ 5.605633] Goodix-TS 11-0014: 11-0014 supply VDDIO not found, using dummy regulator
[ 5.606407] Goodix-TS 11-0014: i2c test failed attempt 1: -6
[ 5.652077] Goodix-TS 11-0014: i2c test failed attempt 2: -6
[ 5.701486] Goodix-TS 11-0014: I2C communication failure: -6

And check i2c is working:
ls /dev/i2c-*
/dev/i2c-11

And your HyperPixel 4 touch is showing up (there should be an address blocked out with UU in the below command):

pi@raspberrypi:~ ls /dev/i2c-* /dev/i2c-1 /dev/i2c-11 pi@raspberrypi:~ i2cdetect -y 11
