During the initial setup, if the offset calibrator fails, the audio offset will be left at NaNms, rendering you in a softlocked state. If you try to use the plus or minus on either side of it to change it, it doesn't change and stays the same.
When you go into a map with NaNms offset, none of the notes come down, and you're basically just listening to the songs with no input. Re-running the calibrator has the same no notes issue, and so is therefore also impossible to calibrate it via that method as well.
