Pygame Error in karaoke.py when trying to start "video system not initialized"

[Romeo1984]

Setup:
Pi4
Bullseye 64 non-desktop OS (updated)
Miniconda 4.9.2 ARCH 64 (not updated - I did update it in an earlier install, but it broke the HTTP packet retrieval, so I re-stalled it)
Running from SSH:

 (base) pi@pikaraoke:~/pikaraoke $ sudo env PATH=~/miniconda3/bin:$PATH python3 app.py

pygame.error: video system not initialized

I did a search and didn't find any obvious fixes.

Update - I just rebuilt the system based on Ubuntu 22.04.2 64-bit LTS and got the same error.

Making progress. I actually got app.py to start successfully by installing and starting with xvfb-run to give pygame a virtual frame buffer. The QR Code screen has no real video to output to, BUT I was successful in playing an MP4 file with VLC to the standard video out. I now need to figure out how to properly initialize the real video out for pygame.
