HDMI output help

Hello, I have been following this tutorial (AMD Customer Community) for generating a video output on the Pynq-Z2 HDMI out. I have been able to verify the block diagram and export the hardware to Vitis, but in Vitis when I try to run the program I get an error saying:
“Memory write error at 0x100000. Cannot flush CPU cache. APB AP transaction error, DAP status 0xF0000021.”
When I open the hardware manager in Vivado I see this.

From this I assume that my issue is that ARM core is not connected. I have checked over my jtag connector and it seems correct. I am wondering if there is an issue in the way my PS is set up which was not mentioned in the tutorial. Any ideas what my issue could be?
