Thanks for the bug reports! If you have a chance could you post a screenshot of your monitor displaying the tutorial... or is it literally a blank screen?
If unplugging those various other controllers fixed the issue you can probably plug them back in and set the CONTROLLER_INDEX to the right number, sounds like it's probably somewhere in the 1-4 range.
Regarding the speed on the monitor. I'd recommending going into the monitor or graphics settings for your graphics card and set They Bleed Pixels to use 60 fps/hz while keeping vysnc enabled. Disabling vsync by itself may still result in some speed issues unfortunately. This is a known issue with high refresh rate monitors that is unfortunately very difficult to fix in game now, but thankfully easy to work around.
