My issue was I had hardware acceleration disabled, which prevents the game from working because Pixi cannot use WebGL. It might be prudent to include the legacy 2D canvas fallback, or detect the error.
That could be it, I thought pixi would handle that automatically. Hopefully that should be the main issue then.
Edit: Could re-create the issue thanks to your tip, got lucky that there was a pixijs update a few days ago which provided a automatic fallback so it took less work than I was expecting 😅
